摘要：

A convenient one pot synthesis of 1.3,5 triaryl-1,2,3,4-tetrahydro-4-oxo-7-methyl-2-thioxo-5H-pyrano[2,3-d]pyrimidines (la-y) has been achieved by the condensation of different 2-thiobarbituric acids (2a-h) with benzylideneacetones (3a-d) in glacial acetic acid in the presence of phosphorous pentoxide. © 1990, Taylor & Francis Group, LLC.
