A one-step method to assemble pyrroles fromα,β-unsaturatedimines and acid chlorides has been developed. This reaction is mediated by triphenylphosphine, which eliminates phosphine oxide to allow cyclization. This reaction has been employed to access a diverse range of pyrroles via modulation of the two building blocks and applied as well to the synthesis of lukianol A.
