Asymmetric Diels-Alder reactions of enantiopure 1-methoxy-3-(phenyl-2-hydroxyethylsulfinyl)-1,3-butadienes
摘要:
Enantiopure 1-methoxy-3-(1-phenyl- and 2-phenyl-2-hydroxyethylsulfinyl)-1,3-butadienes were prepared from ethyl maudelate. Diets-Alder reactions with methyl acrylate proceeded with complete regioselectivity and high diastereoselectivity.
