Kinetic Resolution of 2-Oxazolidinones via Catalytic, Enantioselective N-Acylation
摘要:
Kinetic resolution of racemic 2-oxazolidinones via catalytic, enantioselective N-acylation has been achieved for the first time and with outstanding selectivities.

A love of self: Narcissistic macrocyclic rings self‐assemble into highly ordered, chiral [2]‐catenanes displaying high component diastereoselectivity. The picture shows one such structure. One ring is shown in a space‐filling representation (C green, O red, N blue, H gray), while the other is shown as orange sticks.
