Synthesis of 2H-pyrroles by treatment of pyrrolidines with DDQ
摘要:
A mild and efficient synthesis of 2,2-dialkyl-3,5-diaryl-2H-pyrroles is described. Treatment of 2,2-dialkyl-3,5-diarylpyrrolidines with DDQ in dioxane for 12-24 h at rt afforded the corresponding 2H-pyrroles in 55-81% overall yields. (C) 2003 Elsevier Science Ltd. All rights reserved.
