Vinyl ethers and sulfides containing antioxidant functional groups

Vinyl ethers and sulfides containing antioxidant functional groups Methods for the synthesis of compounds combining in the molecule fragments of known antioxidants with reactive vinyloxy and vinylthio groups have been developed. Transesterification of methyl 3-[3,5-di(tert-butyl)-4-hydroxyphenyl]propionate with 2-(vinyloxy)- or 2-(vinylthio)-ethanol furnished the high yields of 2-(vinyloxy)- and 2-(vinylthio)ethyl 3-[3,5-di(tert-butyl)-4-hydroxyphenyl]propionates.

Abstract

Methods for the synthesis of compounds combining in the molecule fragments of known antioxidants with reactive vinyloxy and vinylthio groups have been developed. Transesterification of methyl 3-[3,5-di(tert-butyl)-4-hydroxyphenyl]propionate with 2-(vinyloxy)- or 2-(vinylthio)-ethanol furnished the high yields of 2-(vinyloxy)- and 2-(vinylthio)ethyl 3-[3,5-di(tert-butyl)-4-hydroxyphenyl]propionates. The reaction of 2-[(vinyloxy)ethoxymethyl]- and 2-[(vinylthio)-ethoxymethyl]oxiranes with 2,2,6,6-tetramethylpiperidin-4-ol and 4-aminodiphenylamine proceeds with the oxirane ring opening and leads to the corresponding vinyloxy and vinylthio derivatives of 2,2,6,6-tetramethylpiperidin-4-ol and mono- and bisvinyloxy and -vinyl- thio derivatives of 4-aminodiphenylamine at the primary amino group.
