Highly efficient and enantioselective biotransformations of racemic azetidine-2-carbonitriles and their synthetic applications
(Chemical Equation Presented) Catalyzed by the Rhodococcus erythropolis AJ270 whole cell catalyst in neutral aqueous buffer at 30 °C, a number of racemic 1-benzylazetidine-2-carbonitriles, trans-1-benzyl-4-methylazetidine-2- carbonitrile, and 1-benzyl-2-m
Enzymatic resolution of methyl N-alkyl-azetidine-2-carboxylates by Candida antarctica lipase-mediated ammoniolysis
A facile method for the synthesis of optically active azetidine-2- carboxylic acid derivatives is presented Racemic N-alkylated azetidine esters are resolved by lipase from Candida antarctica in an ammoniolysis reaction, and both the S-amide and the R-ester are obtained with excellent stereoselectivity.
