New scaffolds for the stereoselective synthesis of diversely functionalized chiral enantiopure indolizidines and pyrrolizidines were synthesized from the cross and ring-closing metathesis reactions of appropriate intermediates, readily available from l-pyroglutamic acid. The versatility of this strategy was demonstrated by the synthesis of an indolizidine-based azasugar analogue and of the natural
从合适的中间体的交叉和闭环易位反应合成了用于立体选择性地合成功能多样的手性对映体纯的吲哚并咪唑和吡咯并核苷的新支架,这些中间体容易从1-焦谷氨酸获得。该策略的多功能性通过基于吲哚并立定的氮杂糖类似物和天然生物碱(+)-单morine的合成得到证明。
