anhydro-2-(2-Allyloxyphenyl)-3,5-diphenyl-4-hydroxy-6-oxo-1,3-thiazinium hydroxide and the corresponding ethynyl derivative underwent ready thermal 1,4-dipolar cycloaddition to give a 1:1-cycloadduct (whose structure was determined by X-ray crystallograph
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.
