Polycyclic N-Hetero Compounds. VI. Synthesis of 11, 13, 15-Triazasteroidal Compounds and Correction of the Structures of Its Intermediates

Abstract

11, 13, 15-Triazasteroidal compounds, that is, 1, 2, 4, 5-tetrahydrobenz [h] imidazo [1, 2-c]-quinazolines (IV) were synthesized by the new route. Its intermediates (VII, VIII) were compared with the previous intermediates (II, III). II and III were corrected to II'and III'respectively.
