- W2022157477 abstract "(4-Methoxybenzyl)magnesium chloride was acylated with dialkyl oxalates 14A, B, D or S, S-di- TERT-butyl dithiooxalate ( 14C) to give 2-hydroxy-3-(4-methoxyphenyl)acrylates and -thioacrylates 17A- D. Esterification with phenylacetic anhydride or (4-methoxyphenyl)acetic acid/ N, N′-dicyclohexylcarbodiimide stereoselectively furnished 2-(arylacetoxy)-3-(4-methoxyphenyl)acrylates and thioacrylates ( Z)- 18A- D. Treating the latter with potassium TERT-butoxide induced Dieckmann condensations, which led to isomerically pure pulvinones 1G, H in up to 88% yield." @default.
