A convenient method for the preparation of enantiomerically pure P-chiral dicyclohexylammonium 2-(phosphinyl)acrylates 6 and 7 is presented. The synthesis of α-methylene-δ-valerolactone 5a with enantiomeric excesses of 85% and 80% has been developed. The
Evaluating dynamic kinetic resolution strategies in the asymmetric hydrosilylation of cyclic ketimines

Attempts at performing dynamic kinetic resolution on a series of cyclic ketimines by making use of an asymmetric organocatalysed hydrosilylation gave modest conversion and moderate to good enantioselectivities. In the case of α-tetralone derivatives, the use of an N-benzyl protecting group was found to be crucial in obtaining enhanced levels of selectivity.
