, p. 1571 - 1575 (2006)
FSM-16, a mesoporous silica, was found to catalyze oxidative photo-decarboxylation of α-hydroxy carboxylic acid, phenyl acetic acid derivatives and N-acyl-protected α-amino acids to afford the corresponding carbonyl compounds. Furthermore, FSM-16 proved to be re-usable by re-calcination at 450°C after the reaction.

Benzyl acetylcarbamate potassium salt (BENAC-K) has been developed as a simple nucleophilic acetamide equivalent. A broad variety of alkyl halides were converted into benzyloxycarbonyl-protected N -alkylacetamides in high yields by simple treatment with an almost equimolar (1.1 equiv) amount of BENAC-K in a polar solvent.

, p. 3799 - 3808 (2016/05/24)
A total synthesis of brevisamide, a marine monocyclic ether amide isolated from the dinoflagellate Karenia brevis, has been achieved in 18 steps starting from 4-(benzyloxy)butanol. The synthesis involves oxiranyl anion coupling between an epoxy sulfone and a triflate, intramolecular etherification of a hydroxy-bromoketone, diastereoselective introduction of the axial methyl group by hydroxyl-directed hydrogenation of an exocyclic olefin, and installation of an acetamide side chain by nucleophilic substitution of an N-acetyl carbamate. The dienal side chain is assembled using a Horner-Wadsworth-Emmons reaction to complete the synthesis.
