Synthesis of highly functionalized homochiral azetidines and azetidine-2-carboxylic esters

Tetrahedron, 1993
Abstract Homochiral (2S, 3S)-3-benzyloxy-2-formyl-azetidines 2, (2S, 3S)-3-benzyloxy-2-carbomethoxy-azetidines 3 and the highly strained (2S)-N-p-methoxyphenyl-2-silyloxymethyl-3-azetidinone 4 were successfully synthesized starting from diethyl-L-tartrate.

Novel antibacterial azetidine lincosamides

Bioorganic & Medicinal Chemistry Letters, 2008
The synthesis and evaluation of novel azetidine lincosamides 1 are described. Eleven new (3-trans-alkyl)azetidine-2-carboxylic acids were synthesized via alkylation of N-TBS-4-oxo-azetidine-2-carboxylic acid and subsequent elaboration then coupled to 7-chloro-1-methylthio-lincosamine.
