A new and efficient one-pot synthesis of polysubstituted pyrrole derivatives by three-component reaction between dialkyl acetylenedicarboxylates, triphenylphosphine, 2-aminopyridin derivatives in the presence of arylglyoxals is described. The reactions were performed in dichloromethane at room temperature and neutral conditions and afforded high yields of products.

New Compounds

A one-pot synthesis of a novel series of chromeno-imidazo-pyridinone derivatives from 3-[(2-hydroxyphenyl)-3-oxoprop-1-en-1-yl]chromones and ethane-1,2-diamine at room temperature under catalyst-free conditions has been successfully developed. This approach involves a tandem aza-Michael addition reaction, a chromone-to-chromanone rearrangement, and a heterocyclization sequence, leading to chromeno-imidazo-pyridinone polyheterocycles. The structure and absolute configurations of the new compounds were elucidated by a combination of 1D- and 2D-NMR analyses and single-crystal X-ray diffraction.

First Time

A high-yielding cyclocondensation of 4-hydroxycoumarin, phenylglyoxal monohydrate, and heteroarylamines proceeds without catalysis, which gives novel functionalized furo[3,2-c]coumarins and heteroarylamino alkylation of coumarin products in acetonitrile under reflux, is reported for the first time. This tandem process involves sequentially an aldol condensation, Michael addition, a ring closure, and dehydration reaction.
