  描述：

  (E)-4-Dimethylsilanyloxy-3-methyl-4-phenyl-but-2-enoic acid methyl ester 在 Pt Karstedt catalyst 作用下， 以 1,2-二氯乙烷 为溶剂， 生成 (4R,5S)-2,2,4-Trimethyl-5-phenyl-[1,2]oxasilolane-3-carboxylic acid methyl ester 、 (4R,5R)-2,2,4-Trimethyl-5-phenyl-[1,2]oxasilolane-3-carboxylic acid methyl ester

  名称：

  A stereochemical study on the intramolecular hydrosilylation of α,β-unsaturated esters

  摘要：

  The intramokcular hydrosilylation of several 3-methyl-4-siloxy-2-butenoates afforded cis disubstituted lactones after desilylation. The diastereoinduction was sensitive to the bulk of the allylic substituent, but not to the groups on silicon. The origin of asymmetric induction is believed to be the A1,2 strain from the beta-methyl group.
