Synthesis and antimicrobial activity of some benzofuran derivatives
Hishmat,Atta Sh.,Atalla,Abd el Rahman
, p. 784 - 786 (2007/10/02)
The Friedel-Craft's acylation of 2,3-diphenyl-5-methylbenzofuran-5 -methylbezofuran 1a with succinic anhydride gives β-(2,3-diphenyl-5-methylbenzofuranoyl)propionic acid 1b. Acid 1b reacts with hydrazines yielding the corresponding tetrahydropyridazinones
