摘要：

The presence of a borane axial group in compound 14 induces a regio and stereospecific O-1(2) cycloaddition at low temperature. This selectivity together with that obtained during the lithium liquid ammonia reduction of the 4a-beta-hydroxyenone 6, allows a short and stereospecific synthesis of the (+/-) epi-7,7a tecomanine 5, an unnatural and undescribed isomer of the tecomanine 1.
