Pummerer reaction of sulfoxides in acetic anhydride catalyzed by Al-MCM-41
The Pummerer reaction of acetic anhydride with both alkyl aryl sulfoxides and dialkyl sulfoxides was efficiently promoted by a mesoporous aluminosilicate Al-MCM-41 to afford the corresponding α-acetoxy sulfides in high yields. The catalyst was easily reco

SYNTHESIS OF OXACYCLIC CARBOXYLIC ESTERS THROUGH RING CLOSURE OF Α-ALKOXY ESTER FREE RADICALS
Cyclizations of 1-methoxycarbonyl-2-oxa-5-hexenyl (and related) radical intermediates, generated from phenylthio precursors, proceed in good yields and mainly lead to substituted 2-tetrahydrofurancarboxylic esters.
