摘要：

A synthesis of 2-substituted-1,3-dienes is reported which uses silicon as a control element: Eight aldehydes were converted into alpha-silyl ketones by treatment with trimethylsilylmethylmagnesium chloride and rapid Collins oxidation. Addition of vinylmagnesium bromide to the resulting alpha-silyl ketones, followed by Peterson elimination, gave a series of dienes. The route was used to make (4S)-3-methylene-t-[(phenylmethoxy)methoxy]pent-1-ene from (-)-ethyl lactate; low asymmetric induction was observed in the Diels-Alder reactions of this diene with diethyl fumarate and N-phenylmaleimide.
