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.

苯并呋喃甲胺5a - c与N -Boc-3-(4-
氰基苯基)
恶唑烷反应生成N -Boc
肼7a - c,然后通过脱保护和环化反应将其转化为三唑4a - c,强效抗芳香化酶剂,总收率高,对映体过量高。
