An Asymmetric Synthesis of cis-5-Alkylproline Derivatives

We have developed a versatile and convenient synthesis of cis-5-alkylprolinamides.Protection/activation of the α-carboxylic acid function of N-benzyloxycarbonyl-L-glutamic acid (Z-L-Glu-OH) by reaction with H2CO to form an N-Z-oxazolidinone ring allowed t
