| Abstract: | Alkylation of anions derived from 5-ethylthio-4-substituted furanones (1–3) is described. The regioselectivity depends on the alkylating agent but mainly on the nature of the substituent. The alkylation of 4-methoxyfuranone 3 proceeds regioselectively to afford the 5-alkylated derivative as sole product. |
