Microwave-Accelerated O-Alkylation of Carboxylic Acids with O-Alkylisoureas
摘要:
Microwave-assisted beta-alkylations of several carboxylic acids have been performed with three different beta-alkylisoureas. All reactions are significantly faster compared to conventionally heated reactions, while retaining high chemoselectivity. The combination of microwave technology with the use of the solid-supported isourea 3 enables the synthetic chemist to obtain the pure methyl esters starting from the corresponding acids in less than an hour.
Unsaturated acids and macrocyclic lactones Communication 11. Total syntheses of cis-8-hexadecenoic, cis-11-hexadecenoic (palmitovaccenic), cis-7-octadecenoic, and cis-9-hexacosenoic acids
