## Abstract magnified image The cyclocondensation of 5‐hydroxy‐pyrido[2,3‐__d__]pyrimidines **1** with malonates gives pyrano[2β€²,3β€²:4,5]‐pyrido[2,3‐__d__]pyrimidines **2**. Nitration of **1** and reduction with zinc in the presence of carboxylic acids/anhydrides gave 2‐alkyloxazolo[5β€²,4β€²:4,5]pyrid
