An easyaccess to 2-aryl pyrrolidines is the reduction, stereospecific or not, of the corresponding 2-aryl-pyrroline (5-aryl-3,4-dihydro-2H-pyrrole). Preparation of the latter has been carried out from 2-pyrrolidinone using an easy one-pot two-step method for the first time.
A Hofmann Rearrangement-Ring Expansion Cascade for the Synthesis of 1-Pyrrolines: Application to the Synthesis of 2,3-Dihydro-1<i>H</i>-pyrrolo[2,1-<i>a</i>]isoquinolinium Salts
cyclobutanecarboxamide with bis(trifluoroacetoxy)iodobenzene, PhI(OCOCF3)2, resulted in the formation of 1‐pyrroline via Hofmann rearrangement of the former followed by in situ ring expansion reaction of the cyclobutylamine intermediate. Further elaboration of this methodology to the synthesis of 2,3‐dihydro‐1H‐pyrrolo[2,1‐a]isoquinolinium salts has also been described.
