Novel stereocontrolled syntheses of exocyclic γ-oxovinyltrimethylsilanes. A potential route for stereodefined exocyclic tetrasubstituted alkenes
Abstract
The course of the dehydration of α-hydroxy-γ-oxotrimethylsilanes is highly dependent on the conditions to produce stereoselectively (Z)- and (E)-γ-oxovinyltrirnethylsilanes, which are potential precursors for preparation of stereodefined exocyclic tetrasubstituted alkenes.
