An Efficient One-Pot Synthesis of 1-Amino-3-cyano-4-aryl-10-ethoxycarbonylazuleno[2,1-b]pyrans
摘要:
An efficient and easy method for the one-pot three-component synthesis of 2-amino-3-cyano-4-aryl-10-ethoxycarbonylazuleno[2,1-b]pyran derivatives by the three-componenet condensation of ethyl 2-hydroxyazulene-1-carboxylate, aldehydes, and malononitrile in the presence of diazabicyclo[2.2.2]octane (DABCO) has been described.
