Abstract
Chiral rings made easy : Chiral azetidin‐3‐ones have been easily prepared from chiral N‐propargylsulfonamides, which in turn are readily accessible through chiral sulfinamide chemistry (see scheme). Using tert‐butylsulfonyl as the protecting group avoids unnecessary deprotection and reprotection steps, and allows its removal from the azetidine ring under acidic conditions.Keywords
