Prolinethiol ether catalysis in an asymmetric Michael reaction: solvent-free synthesis of functionalized monohaloalkenes.

Ai-Bao Xia et al.

The Journal of organic chemistry, 78(3), 1254-1259 (2013-01-05)

The organocatalytic Michael reaction of ketones with γ-monohalonitrodienes catalyzed by chiral prolinethiol ether under solvent-free conditions was developed. The described method represents a novel approach for accessing highly functionalized monohaloalkenes with α, β-stereocenters of up to >99% ee.

Aryllithiums with increasing steric crowding and lipophilicity prepared from chlorides in diethyl ether. The first directly prepared room-temperature-stable dilithioarenes.

Constantinos G Screttas et al.

Organic letters, 14(22), 5680-5683 (2012-11-02)

A convenient procedure has been developed for the preparation of synthetically useful, room-temperature-stable aryllithiums starting from aryl chlorides and lithium metal. The method provides a route to aryllithiums which have previously not been accessible cleanly or could only be prepared
