Staudinger reaction synthetic utility

Meyers and co-workers have continued their studies to exploit the synthetic potential of a-lithio-formamidines and have now described an efficient synthesis of 2-aryl- or 2-heteroaryl-pyrrolidines and -piperidines (266 ). " Alkylation of formamidines (264) gives intermediates (265) which cyclize in situ after cleavage of the amidine unit. The aza-Wittig reaction has been utilized in a general synthesis of heterocyclic vinylogous ure-thanes and amides (268). Staudinger reaction of azides (267)... [Pg.512]
