Three-Component Condensation of 2,4-Diaminoselenazole with Aldehydes and Meldrum’s Acid: Synthesis of 7-Aryl(alkyl)-Substituted 2-Amino-6,7-dihydro-4H-selenazolo[4,5-b]pyridin-5-ones
摘要:
A method for the synthesis of 7-aryl(alkyl)-substituted 2-amino-6,7-dihydro-4H-selenazolo [4,5-b]pyridin-5-ones 5 based on three-component condensation of in situ-generated 2,4-diaminoselenazole 7 with aromatic (aliphatic) aldehydes 9 and Meldrum's acid 10 was developed.
