Synthesis of enantiomerically pure α-[4-(1-substituted)-1,2,3-triazol-4-yl]-benzylacetamides via microwave-assisted click chemistry: towards new potential antimicrobial agents
Chiral 1-phenyl-2-propynylamines are important building blocks for the synthesis of antifungal and antiaromatase agents related to bifonazole. In this report, a microwave-assisted Cu(I)-catalyzed ‘click chemistry’ approach has been employed to easily generate a small library of enantiomerically pure α-[4-(1-substituted)-1,2,3-triazol-4-yl]benzylacetamides starting from racemic propargylamines. These
Two practical routes for the synthesis of benzhydrylamine derivatives in enantiomerically pure form have been developed. N-Acetylbenzhydrylamines can be synthesised in few steps and good yields starting from 1-aryl-1-propargylamines. The key steps are represented by the alkene-alkyne cross metathesis reaction and alkyne–diene methylene-free tandem-metathesis reaction; these reactions have been performed
