The alkaloids (+)- and (−)-indolizidine 167B were synthesized via radical addition of a carbon radical to a chiral acrylamide. Further cyclization in the presence of BBr3, treatment with ‘nickel boride’ and stereospecific hydrogenation over palladium/carbon in acetic acid were other key steps in this synthesis.
生物碱(+)-和(-)-吲哚唑烷167B是通过向手性丙烯酰胺自由基加成碳原子而合成的。该合成过程中的其他关键步骤是在BBr 3存在下进一步环化,用“硼化镍”处理和在乙酸中钯/碳上的立体有择加氢。
