An Efficient Synthesis of 4-Heterofunction-Substituted 3-(1-Hydroxy)ethylazetidin-2-ones from 3-(1-Hydroxy)ethyl-4-phenylsulfinylazatidin-2-one by Reaction with Silylated Heteronucleophiles

Abstract

3-(1-tert-Butyldimethylsiloxy)ethyl-4-sulfinylazetidin-2-one was reacted with silylated N-, S-, O-, and P-nucleophiles in the presence of a catalytic amount of ZnI₂ to give the corresponding trans-4-heterofunction-substituted azetidin-2-ones in high yelids.
