A novel method has been developed for the direct synthesis of ketene dithioacetals and 2-trimethylsilyl-1,3-dithiane derivatives from 1,3-dithiane.Treatment of 1,3-dithiane (1.0 mol equiv.) with BuLi (1.1 mol equiv.), HMPA (4.0 mol equiv.), and Me3SiSiMe3
CONJUGATE (1,4) ADDITION OF HETEROCYCLIC ACYL ANION EQUIVALENTS TO CYCLIC α-ENONES IN THE PRESENCE OF HEXAMETHYLPHOSPHORIC TRIAMIDE: A GENERAL REACTION
Brown, Charles Allan,Chapa, O.,Yamaichi, A.
, p. 187 - 189 (2007/10/02)
Heterocyclic dithiaorganolithium reagents react with cyclic α-enones in THF to yield only products of carbonyl (1,2) addition; in the presence of 2.0 equivalents of hexamethylphosphoric triamide, the addition proceeds to give nearly exclusively the produc
