Based on the use of phenyl thioether (3S)-7 as a synthetic equivalent to the N- and α-dianions (3S)-2a, a new carbanionic approach to trans-(2R,3S)-2-substituted 3-aminopyrrolidines (10) is described. Application of the method to the asymmetric synthesis of 1-aminopyrrolizidine alkaloid (+)-absouline is also reported.
基于使用苯基硫醚 (3S)-7 作为 N-和 α-二价阴离子 (3S)-2a 的合成等价物,一种新的碳负离子方法用于反式-(2R,3S)-2-取代的 3-氨基吡咯烷( 10) 描述。还报道了该方法在 1-氨基吡咯里西啶生物碱 (+)-absouline 的不对称合成中的应用。
