Title: Metal carbene N-H insertion of chiral alpha,alpha '-dialkyl alpha-diazoketones. A novel and concise method for the stereocontrolled synthesis of fully substituted azetidines
Author: Burtoloso, ACB
Correia, CRD
Abstract: The syntheses of all cis substituted azetidines were accomplished in few steps from L-serine in modest to high yields. The key step was based on a rhodium or copper carbenoid N-H insertion of alpha,alpha'-dialkyl-alpha-diazoketones to furnish cis-2,4-dialkyl-azetidin-3-ones as the only observable diastereoisomers.
