✦ Synopsis
A method for the preparation of a-azido-masked acyl cyanides as synthetic equivalents of N-protected-C-activated a-amino acids was developed using carbon-carbon bond formation between aldehydes and the Masked Acyl Cyanide Reagents, followed by sulfonylation and substitution by azide anion. This method was applied to the synthesis of d-threonine and l-allo-threonine derivatives.
