A novel, simple approach to 2-(1-alkoxyprop-1-enyl)-5-ethenylidene-4,5-dihydro-1,3-thiazoles was disclosed through the reaction of (propargylthio)-2-aza-1,3,5-trienes (readily available from alkoxyallenes, isothiocyanates, and propargyl bromide) with potassium or sodium tert-butoxide (1.1-1.4 equiv) under mild conditions [DMSO/THF (∼1:4-5), ∼-30°, 15-30 min]. The process proceeds through deprotonation of an activated SCH2 group, followed by intramol. [1,5]-ring-closure. Unlike alkyl-, benzyl-, and allylthio-analogs, the exclusive or competitive formation of seven-membered azaheterocycles was not observed This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Related Products of 2253-73-8).
Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Related Products of 2253-73-8
