β-Hydroxydithioesters (5) are obtained via trreatment of mixture of methyl dithioacetate and the appropriate carbonyl compound with sodium hydride in tetrahydrofuran. αβ-Unsaturated dithioesters (1) can be prepared from (5) by way of suitable elimination reactions.Cycloadducts are formed by the reaction of (1) with a number of dienophiles and one diene.
Thiono and Dithio Esters, XXII. α,β-Unsaturated Thiono and Dithio Esters
Hoffmann, Rainer,Hartke, Klaus
, p. 919 - 933 (2007/10/02)
α,β-Unsaturated thiono and dithio esters such as O-ethyl thiocinnamate (3), methyl dithiocinnamate (7), O-ethyl thiocrotonate (17), and O,O-diethyl dithiofumarate (28) have been prepared by thiolysis between 20 and - 75 deg C from the corresponding O- or S-alkylated tertiary amides or thioamides.They tend to dimerize in part by cycloadditions.Methyl dithiocrotonate (24) could only be isolated as the endo-dimer 25.
