A convenient 1,3-dipolar cycloaddition approach to pyridylpyrroles
摘要:
A variety of 2-, 3-, and 4-pyridylpyrroles were synthesized in good to excellent yields via the 1,3-dipolar cycloaddition of symmetrical and unsymmetrical munchnones and nitroalkenes. The unsymmetrical munchnones show moderate to excellent regioselectivity. (C) 2011 Elsevier Ltd. All rights reserved.

Herein, a facile method is developed for the synthesis of vicinal bisphosphine derivatives based on a cascade of hydrophosphinylation, elimination, and hydrophosphinylation of secondary phosphine oxides with nitroalkenes. This cascade reaction provides step-economy access to a series of vicinal bisphosphine derivatives with high to excellent yields (up to 99%). This method was further extended to prepare
