The stereoselective synthesis of a 1,2,3-triazolod-lactone (+)-6 derived from a homoallyl alcohol (S)-(-)-1 backbone was accomplished. 2-Thienyl-substituted allyl alcohol rac-1 was efficiently resolved through enzymatic method with high ee (95%) and known stereochemistry. An enantiomerically enriched azidoalcohol (+)-4 derived from a homoallyl alcohol was subjected to the Huisgen 1,3-dipolar cycloaddition reaction with diethyl acetylenedicarboxylate, followed by intramolecular cyclization of the corresponding cycloadduct (+)-5, to yield the 1,2,3-triazolo-delta-lactone derivative.
