Ketene dithioacetals undergo a Sharpless-type asymmetric oxidation using (+)-DET, Ti(OZPr)4, and cumene hydroperoxide to give the trans bis-sulfoxides 4a-f with essentially complete control of enantioselectivity and dia-stereoselectivity. The high enantio

Excellent yields of ketene thioacetals are obtained from 2-(1- chloroalkyl)-1,3-dithiolanes or 2-(1-chloroalkyl)-1,3-dithianes.
Counterattack Reagent: Hexamethyldisilane in a Direct Synthesis of Ketene Dithioacetals and 2-Trimethylsilyl-1,3-dithiane Derivatives from 1,3-Dithiane

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
RELATIVE REACTIVITY OF 2-DIPHENYLPHOSPHINOYL- AND 2-DIPHENYLTHIOPHOSPHINOYL-2-(1,3)DITHIANYLLITHIUM AS REAGENTS WITTIG-HORNER/COREY-SEEBACH.

The reaction of the title carbanions with several aldehydes and ketones to afford the corresponding ketene dithioketals was studied.It was found that the P=O organolithium reagent reacted with both types of carbonyl substrates in good to excellent yields.
