By an appropriate choice of cation, three of the four possible aldols from the reactions of the chiral a-silyloxy ketone 1 with aldehydes may be obtained. The Z lithium enolate provides 6, the Z boron enolate gives 7, and the E magnesium enolate affords 8.

## Abstract Metathesis polymers of norbornene and 1‐methylnorbornene were prepared using a well‐defined aryloxy(chloro)neopentylidene tungsten initiator which behaves in a stereo and regioselective manner giving predominantly __cis__ polymers and a strong head‐to‐tail bias in the case of 1‐methylno
