Cyclohexyl-based chiral auxiliaries can be used effectively in an asymmetric Pictet-Spengler synthesis of tetrahydroisoquinoline, aporphine and protoberbine alkaloids. Using this strategy, concise asymmetric syntheses of (−)-laudanosine, (+)-glaucine and (+)-xylopinine have been accomplished.
基于环己基的手性助剂可有效地用于四氢异喹啉,阿芬和原小豆碱生物碱的不对称Pictet-Spengler合成中。使用这种策略,已经完成了(-)-月桂肌苷,(+)-月桂氨酸和(+)-木酮素的简明不对称合成。
