Benzyl Methyl (S)-2-(p-Tolylsulfinyl)maleate, an Efficient Dienophile in Asymmetric Diels-Alder Reactions
Alonso, Ines,Carretero, Juan C.,Ruano, Jose L. Garcia
, p. 1499 - 1508 (2007/10/02)
The enantiomerically pure dienophile 3 was readily prepared in a three-step sequence from benzyl acetate and (-)-(S)-menthyl p-toluenesulfinate (46percent overall yield).This vinyl sulfoxide reacted in high
