A new and concise synthesis of enantiopure antipodes of alkaloid cherylline has been devised. The synthetic strategy relies upon the reduction of a diversely and polyprotected diarylenamine bearing a chiral auxiliary. Separation of diastereopure intermediates, concomitant deprotections and intramolecular reductive amination complete the synthesis of the natural (S)-enantiomer and of the unnatural (R)-configured
已经设计了一种新的,简明的生物碱雪茄碱对映体对映体的合成方法。合成策略依赖于减少带有手性助剂的多样化和多保护的二芳胺。非对映体中间体的分离,伴随的脱保护和分子内还原胺化完成了天然(S)-对映异构体和非天然(R)-构型对映体的合成。
