A short, new route to the title tetracyclic substructure of alkaloids, consisting in the nucleophilic attack of an ester α-anion to a pyridinium salt, acid-induced cyclization of the resultant 1,4-dihydropyridine, and stereospecific elaboration of the ethylidene substituent, is reported.
一种简短的生物碱标题四环亚结构的新途径,包括酯α-阴离子对吡啶鎓盐的亲核攻击,酸诱导所得1,4-二氢吡啶的环化以及亚乙基取代基的立体定向修饰,被报道。
