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.

Simple syntheses of enantiopure (E)- and (Z)-3-(alkylsulfinyl)-1-methoxy-1,3-butadienes 2and 3 were provided by the addition of (1S)-isoborneol-10-sulfenic and (S)-phenyl-2-hydroxyethanesulfenic acids 8 to (E)- and (Z)-1-methoxybut-1-en-3-ynes (9) and (10). These additions proceeded with asymmetric induction, the extent of which depended upon the nature of the chiral hydroxyalkyl group. Cycloadditions
