Novel Regiospecific Method for Synthesis of 2‐(3,5‐Diaryl‐4,5‐dihydro‐1H‐pyrazol‐1‐yl)‐4,6‐diarylpyrimidines
摘要:
The facile, regiospecific, one-pot synthesis of 2-(3,5-diaryl-4,5-dihydro-1H-pyrazol-1-yl)-4,6-diarylpyrimidines derivatives has been described, involving a [3+2] and [3+3] cyclocondensation between the ,-unsaturated ketones and aminoguanidine bicarbonate.
