Chiral azole derivatives. Part 5: † †For Part 4, see Ref. 1. Synthesis of enantiomerically pure 1-[α-(benzofuran-2-yl)arylmethyl]-1 H -1,2,4-triazoles, antifungal and antiaromatase agents
have been reacted with N-Boc-3-(4-cyanophenyl)oxaziridine to give N-Boc-hydrazines 7a–c, which have in turn been transformed by deprotection and cyclisation into triazoles 4a–c, potent antiaromatase agents, in good overall yield and with high enantiomeric excess.
