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.

The aldol condensation between 2,3-diphenyl-4-thiazolidinone and aromatic aldehydes, which cannot be effected by the usual catalysts used in the analogous reactions of 2-thiono-, 2-oxo-, and 2-imino-4-thiazolidinones, was achieved by the use of ethoxide ion. The structure of the 2,3-diphenyl-5-arylidene-4-thiazolidinone was confirmed by ultraviolet spectral data.
