Highly regioselective one-pot synthesis of 7-hydroxy-6-methylphthalide from 3-hydroxy-4-methylbenzylalcohol

7-Hydroxy-6-methylphthalide 2 was synthesized with high regioselectivity and moderate yield using a novel one-pot synthesis that employed 3-hydroxy-4-methylbenzylalcohol 1 and formaldehyde in the presence of tin(IV) chloride as catalyst and triethylamine

Pyrolysis of O-Allyl Salicylic Amides and Esters, and Related Compounds: Foemation of Isoindolones and Phthalides

Flash vacuum pyrolysis of O-allyl salicylic alkylamides and alkyl esters gives isoindolones and phthalides, respectively, in low (20-40percent) yield.The mechanism involves generation of the phenoxyl radical, regiospecific hydrogen-atom transfer from the alkylamide (or alkyl ester) group and cyclization.A similar sequence was observed with thiophenoxyl radicals.
