New carbon-carbon bond formation through oxyallylation of enoxysilanes with sulfur dioxide adduct of 1-methoxybutadiene. Stereoselective synthesis of (Z)-4-methoxy-6-oxoalk-2-enyl methyl sulfones
Deguin, Brigitte,Roulet, Jean-Michel,Vogel, Pierre
, p. 6197 - 6200 (1997)
Mixtures of 1-methoxybutadiene, trimethylsilyl enol ethers, SO2 and a Lewis acid catalyst generate trimethylsilyl (Z)-4-methoxy-6-oxoalk-2-enesulfinates that can be converted into 4-methoxy-6-oxoalk-2-enyl methyl sulfones and 5-alkyl-4-methoxy-6-oxoalk-2-enyl methyl sulfones with 100% (Z) selectivity and good syn diastereoselectivity for the 5-alkyl and 4-methoxy substituents.

Trimethylsilyl triflate is a powerful silylating agent for organic compounds and acts as a catalyst which accelerates a variety of nucleophilic reactions in aprotic media.The reactions proceed via one-center, electrophilic coordination of the silyl group to hetero functional groups and exhibit unique selectivities.
