Abstract
NEW MATERIAL:3-Acylthiazolidine-3-thione of formulaI: (R1 is hydrocarbon group which may have an inert substituent).
EXAMPLE: 3-Benzoylthiazolidine-2-thione.
USE: Useful as an intermediate for synthesis because the compound can be readily led to an aldehyde by reduction with an organoaluminum monohalide or its complex compound, and by hydrolysis in a high yield.
PROCESS: A corboxylic acid of formula II is reacted with thiazolidine-2-thione of formula III in the presence of a tertiary amine and a quaternary ammonium salt of a heterocyclic compound wherein a halogen atom is bonded to the carbon atom adjacent to the nitrogen atom, e.g. 2-halobenzoxaxonium salt, such as a 2-halopyridinium salt, 2-chloro-3-methylbenzoxazonium chloride, etc. to give the compound of formulaI.
