Bakers’ yeast-catalyzed reductive cleavage of 3-aryl-2,1-benzisoxazoles and its quaternary salts: an efficient green synthesis of 2-aminobenzophenones
摘要:
3-Aryl-2,1-benzisoxazoles and its salts underwent reductive cleavage of the N-O bond leading to 2-aminobenzophenones with bakers' yeast under non-fermenting conditions in aqueous media. The procedure gives excellent yields of 2-alkylamino- and 2-aminobenzophenones.
