The stereospecific synthesis of the monoterpene alkaloids (−)-α-skytanthine ((−)-2), (−)-N -demethyle-δ-sky-tanthine((−)-7), and (+)-epidihydrotecomanine (+)-4 was achieved from a common intermediate 22, which in turn was obtained from (1R,4S,1′S)-2-(1′-phenylethyl)-2-azabicyclo[2.2.1]hept-5-ene (10),via a ketene aza-Claisen rearrangement. The piperidine derivative (+)-31, formally the aza-analogue
单萜生物碱(-)-α-天丹氨酸((-)- 2),(-)- N-脱甲基e-δ-天丹氨酸((-)- 7)和(+)-表二氢水鸟嘌呤( +)- 4由共同的中间体22获得,而中间体22又由(1 R,4 S,1 'S)-2-(1'-苯乙基)-2-氮杂双环[2.2.1] hept-5获得-烯(10),通过乙烯酮氮杂-克莱森重排。哌啶衍生物(+)- 31,正式是(+)-异iridomyrmecin的氮杂-类似物,也是从相同的中间体22中获得的。
