  • Many techniques have been devised for the decarboalkoxylation of substituted ß-ketoesters (compare Diethyl­ malonate, A15468); for reviews, see: Synthesis, 805, 893 (1982). Enolisable ß-keto esters can be decarboalkoxylated by heating in toluene in the presence of a catalytic amount of DMAP. Other bases are ineffective: J. Org. Chem., 54, 3474 (1989).
  • Merck: 14,3758 Beilstein:3(4)1528
  • Under the conditions of the classical acetoacetic ester route to methyl ketones [see, e.g.: Org. Synth. Coll., 1, 248, 351 (1941)], varying amounts of O-alkylation occur. Regioselective C-alkylation can be obtained by phase-transfer procedures: J. Org. Chem., 39, 3271 (1974). For improved alkylation using TBAB, see: Org. Prep. Proced. Int., 26, 469 (1994).
