[Report] Catalytic asymmetric hydroamination of unactivated internal olefins to aliphatic amines

by Yang Yang
Catalytic assembly of enantiopure aliphatic amines from abundant and readily available precursors has long been recognized as a paramount challenge in synthetic chemistry. Here, we describe a mild and general copper-catalyzed hydroamination that effectively converts unactivated internal olefins—an important yet unexploited class of abundant feedstock chemicals—into highly enantioenriched α-branched amines (≥96% enantiomeric excess) featuring two minimally differentiated aliphatic substituents. This method provides a powerful means to access a broad range of advanced, highly functionalized enantioenriched amines of interest in pharmaceutical research and other areas.

Macroscopic 3D Porous Graphitic Carbon Nitride Monolith for Enhanced Photocatalytic Hydrogen Evolution

by Qinghua Liang, Zhi Li, Xiaoliang Yu, Zheng-Hong Huang, Feiyu Kang, Quan-Hong Yang
Thumbnail image of graphical abstract

A macroscopic 3D porous graphitic carbon nitride (g-CN) monolith is prepared by the one-step thermal polymerization of urea inside the framework of a commercial melamine sponge and exhibits improved photocatalytic water splitting performance for hydrogen evolution compared to g-CN powder due to 3D porous interconnected network, larger specific surface area, better visible light capture, and superior charge separation efficiency.

Catalytic Ring Expansion of Cyclic Hemiaminals for the Synthesis of Medium-Ring Lactams

by Wanxiang Zhao, Hui Qian, Zigang Li, Jianwei Sun

Abstract

A mild and efficient intermolecular ring-expansion approach was developed for the synthesis of medium-ring lactams by using siloxy alkynes. Key to success is the suitable combination of a superior catalyst and an exceptional nitrogen-protecting group. Control experiments indicated that the reaction is remarkably selective toward the desired lactam formation, even with many possible non-productive pathways.

Growth rings: A mild catalytic synthesis of medium-ring lactams through ring expansion of cyclic hemiaminals was developed. This synthetically useful method also gives insight into the reactivity of both siloxy alkynes and N-acyliminium analogues.

LEGO Adds Even More Female STEM Minifigs, & You Can Vote for Lovelace, Curie, & Others!

by Jill Pantozzi

LEGOstemVote3We feel that showing kids you can aspire to any career, regardless of gender, is important. That’s why we’re always excited when we see LEGO sets depicting female minifigs in a variety of careers, especially STEM. Take a look at some items currently available in the LEGO store while perusing some of the new Ideas projects worthy of your votes!

Scientific American has alerted us to a few new LEGO sets you might be interested in.

A few items in their space port tag include these minifigs:

Screen Shot 2015-07-01 at 2.36.45 PM

LEGOstemAerospace

Space Scientist

LadyAstronaut

Utility Shuttle Astronaut – Female

ServiceCar

Service Car Female Driver

And there’s the McLaren Mercedes Pit Stop:

LEGOstemMercedesPit2

McLaren Mercedes Pit Crew Member, Female

LEGOstemSeaDive

Deep Sea Submariner Female

Maia Weinstock says LEGO’s Deep Sea Helicopter set is an homage to oceanographer Sylvia Earle. You can check out more in the Deep Sea Explorers section here.

While these are all AMAZING, Weinstock also notes that with the exception of a branded Doc McStuffins‘ Duplo set, “there are no women of color among the new STEM professionals.”

Ok, now onto the voting portion. You know folks can submit ideas to become real LEGO sets? Well there are some fantastic examples right now. For instance, the “Scientists in History” set created by Mibitat.

LEGOstemVote1

They write:

“Currently proposed are 8 scientist vignettes, of which 3 or 4 (voted for by you) could be included in the set:

  • Charles Darwin is observing a monkey in a tree as he ponders his theory of evolution, struggling for acceptance from the people.
  • Alan Turing, pioneering computer scientist,is in his lab working on a code-breaking computer.
  • Mary Anning is down in Dorset trying to extract some fossils.
  • Marie Curie is in her lab with her equipment as she experiments with radioactivity
  • Thomas Edison is in his workshop with his incandescent lamp and gramophone
  • Nikola Tesla is in his lab as he observes his Tesla coil behind the safety of a Faraday cage.
  • Rosalind Franklin is using x-ray crystallography to observe the structure of DNA.
  • Lise Meitner is experimenting with atoms in her lab as she comes up with her theory of nuclear fission.”

LEGOstemVote2 LEGOstemVote4

Then we’ve got Lovelace & Babbage:

LEGOstemVote5

They write:

Ada Lovelace (1815-1852) is widely credited as the first computer scientist and Charles Babbage (1791-1871) is best remembered for originating the concept of a programmable computer. Together they collaborated on Babbage’s early mechanical general-purpose computer, the Analytical Engine. Whilst never fully built in their lifetime, Lovelace’s notes on the engine include what is recognised as the first algorithm intended to be carried out by a machine. Because of this, she is often regarded as the first computer programmer.

And, “Help Ada Junior with her maths homework in the miniature classroom, but just make sure the creepy bat doesn’t steal her beloved teddy bear.”

I die.

LEGOlovelaceAnd finally, a real geologist has created a set showcasing her work! Circe Verba, research geologicst at the National Energy Technology Laboratory writes:

“I’m a female research geologist with a love of legos- this is a sample of my career. The scene here shows research geologists discovering minerals in a limestone rock formation and the characterization of the minerals in the laboratory.

  • The entire project has 213 pieces total. 
  • Field geology: A female and male geologist with a dog (there’s always the obligatory geology dog) exploring a crystal cave system complete with stratigraphic layers. Accessory pieces include:  compass/brunton, rock hammer, shovel, and a geology dog.
  • Petrographic laboratory: Petrographic laboratory: Mineral analysis performed with a light
    microscope and a scanning electron microscope (SEM) complete with
    an electron backscatter detector to distinguish phases and an energy dispersive
    X-ray spectrometer (EDS) to determine elemental composition using
    microanalysis software.”

Will you be voting for any of these?

Acylation of (Hetero)Arenes through CH Activation with Aroyl Surrogates

by Xiao-Feng Wu

Abstract

In this Minireview, the major achievements in the acylation of arenes and heteroarenes by C[BOND]H activation with aroyl groups are summarized and discussed. As the products are carbonyl-containing compounds that are typical products from carbonylation chemistry, the possible inspirations for these reactions are also discussed, as are mechanistic issues and possible problems for carbonylative diaryl ketone synthesis by C[BOND]H activation.
