A possible biosynthetic pathway of bis-α-substituent pyrrolidine alkaloids was proposed. Based on the proposed biosynthetic pathway, six pyrrolozoxazine alkaloids and one N-alkyl-5-hydroxymethyl-pyrrole-2-carbaldehyde alkaloid were synthesized. In a mixture of acetic acid and triethylamine, condensation of d-fructose and d-amino acids produced pyrrolozoxazine alkaloids. Replacing d-amino acids with
提出了双α-取代基吡咯烷生物碱的可能的生物合成途径。基于拟议的生物合成途径,合成了6种吡咯并恶嗪生物碱和1种N-烷基-5-羟甲基-吡咯-2-甲醛甲醛生物碱。在乙酸和三乙胺的混合物中,d-果糖和d-氨基酸的缩合产生吡咯并恶嗪生物碱。用酪胺取代d-氨基酸可得到吡咯并鸟氨酸-N-烷基-5-羟甲基-吡咯-2-甲醛生物碱。
