The preparation of ring-A fused pyrimidines at the steroidal 2,3-position is herein described. The novel steroidal pyrimidines were prepared from the solid phase three-component reaction of 2-hydroxymethylene-3-keto steroids, arylaldehydes and ammonium acetate under microwave irradiation.

developed for the synthesis of fused steroidal and non-steroidal pyrimidines from β-halo-α,β-unsaturated aldehydes under microwave irradiation. The β-halo-α,β-unsaturated aldehydes are synthesized from corresponding ketones using Vilsmeier formylation reaction. This synthetic protocol is utilized to synthesize some more novel steroidal pyrimidine derivatives and are currently being evaluated for their biological
