(R)-12a underwent ‘click’ reactions with diethyl acetylenedicarboxylate and phenylacetylene to produce functionalized chiral triazoles 14 and 15, respectively. The easy preparation of the starting nitrile substrates, highlyefficient and enantioselective biotransformation reactions, and versatile utility of the resulting functionalized azido carboxylic acids and amidederivatives, render this method very
