Catalyst free conjugate addition of indoles and pyrroles to nitro alkenes under solvent free condition (SFC): an effective greener route to access 3-(2-nitro-1-phenylethyl)-1H-indole and 2-(2-nitro-1-phenylethyl)-1H-pyrrole derivatives
摘要:
Catalyst free conjugate addition of reactive hetero aromatics (pyrrole and indoles) to nitro alkenes under solvent free condition is described. This method provides several advantages, such as operational simplicity, solvent-free conditions and good yields of products. Also it is environmentally friendly and more cost effective alternative to existing protocols. (C) 2010 Elsevier Ltd. All rights reserved.

A catalyst free aqueous-mediated alkylation of indoles with various beta-nitrostyrenes was performed at elevated temperature. No catalyst, clean reaction conditions, simple workup procedure, easy isolation, viability for large scale preparation, and environmentally acceptable medium are the best features in this process.
