Org Lett. 2004 Apr 15;6(8):1301-4. doi: 10.1021/ol0497382.

Effective kinetic resolutions of acyclic allylic acetates and benzoates have been obtained using a palladium/(S)-BINAP(S) catalyst system. Unusually large preferences for the formation of branched alkylation products from 3-but-2-enyl and crotyl substrates have been observed. [reaction: see text]
