|Title:||Metal Carbene N-h Insertion Of Chiral α, α′-dialkyl α-diazoketones. A Novel And Concise Method For The Stereocontrolled Synthesis Of Fully Substituted Azetidines|
|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 α,α′- dialkyl-α-diazoketones to furnish cis-2,4-dialkyl-azetidin-3-ones as the only observable diastereoisomers. © 2004 Elsevier Ltd.
