title: Estrano[17,16-e]pyrimidine-peptide conjugates.
abstract: The preparation of a steroidal heterocycle linked to the tripeptide Cys-Gly-Cys is described. Initially, an estrane-derived steroidal heterocycle containing an aminopyrimidine ring fused to the 16,17-position of the steroidal nucleus was synthesized. Thereafter, protected amino acids were coupled iteratively by the DCC method, commencing at the amino group of the aminopyrimidine unit.
