Synthesis of 2-Amino-4-aryl-3-cyano-4H-pyrano and 2-Amino-3-cyanothieno Derivatives of Cyclopentanonopimaric Acid
摘要:
Condensation of cyclopentanonopimaric acid with malononitrile in the presence of p-methoxybenzaldehyde or elemental sulfur gave the corresponding fused 2-amino-3-cyano-4-(4-methoxyphenyl)-4H-pyrano and 2-amino-3-cyanothieno derivatives.
