Given the importance of amine compounds, methods for their synthesis continue to be in high demand. Now, a palladium-catalysed strategy has been developed for the selective oxidative amination of unactivated olefins with Lewis basic amines, via C(sp3)–H activation, forming architecturally versatile and functionally diverse allylamines in a single step.

Sigillin A is a unique polychlorinated, insect repellent natural product, isolated recently from springtails. During the exploitation of an access to such compounds using a trichloromethyl-anion-induced epoxide opening as key step a new synthetic compound was found. A five-step cascade reaction leads to an oxeto[2,3,4-ij]isochromene compound, including a rare oxetane acetal as well as an trichloroenol ether group. Biological data on the antibacterial properties of this compound and sigillin A are reported as well.
