The enantioselective total synthesis of micropine, an unusual 2,6-disubstituted piperidine alkaloid, and epimicropine, through mercuric trifluoroacetate-catalysed intramolecular alkenylamide cyclisation is described. The synthesis proceeds from L-serine and affords material of the same positive sign of optical rotation as the natural product thereby confirming the absolute stereochemistry of micropine
描述了通过三氟乙酸乙酸汞催化的分子内链烯基酰胺环化反应,对映体选择性合成了松果,一种不寻常的2,6-二取代哌啶生物碱和一种表观松果。合成从L-丝氨酸开始,并提供与天然产物相同的旋光正符号的物质,从而证实了松木的绝对立体化学。
