M. Ueki et al., TRANSFORMATION OF ACYLOIN O-ACYL DERIVATIVES TO KETONES USING TETRABUTYLAMMONIUM FLUORIDE-THIOL SYSTEM, Tetrahedron letters, 36(41), 1995, pp. 7467-7470
The treatment of acyloin (alpha-hydroxyketone) O-acyl derivatives with
tetrabutylammonium fluoride hydrate (TBAF . xH(2)O)-1,3-propanedithio
l system gave the corresponding ketones. Further, it was found that N-
methylmorpholine added could prevent the concomitant of unidentified c
ompounds to give the pure products in high yields.
