All four diastereomers of the trisubstituted piperidine−alkaloids of the veratramine and jervine type were synthesized with complete stereocontrol starting from enantiopure citronellic acids. The flexible, high-yielding, and scalable route described here will facilitate convergent syntheses and give access to analogues of cyclopamine and other biologically active and diverse steroid alkaloids.
从对映体纯的香茅酸开始,以完全的立体控制合成了维他命胺和果菊型的三取代哌啶-生物碱的所有四种非对映异构体。本文所述的灵活,高产且可扩展的途径将有助于融合合成,并使人们能够获得环巴胺和其他具有生物活性的类固醇生物碱的类似物。
