structural reorganization of allyl benzyl and propargylsulfanyl substituted 2 aza 1 3 5 trienes in t buok thf dmso access to rare functionalized 2 Thiazolines
Tetrahedron Letters, 2014Co-Authors: N. A. Nedolya, O A Tarasova, A I Albanov, B A TrofimovAbstract:Abstract Treatment of (allyl-, benzyl-, and propargylsulfanyl)-substituted 2-aza-1,3,5-trienes, which are readily accessible from lithiated methoxyallene, isopropyl isothiocyanate, and allyl, benzyl, or propargyl bromide, respectively, with t-BuOK in THF/DMSO resulted in the unexpected formation of 2-thiazoline derivatives along with seven-membered azaheterocycles [in the case of (allyl- and benzylsulfanyl)-substituted 2-aza-1,3,5-trienes]. An unprecedented structural reorganization of the azatrienes into 2-Thiazolines presumably occurs via α-deprotonation of the substituents at the sulfur atom followed by intramolecular [1,5]-cyclization. Deprotonation of the ketimine fragment of the same molecule followed by [1,7]-electrocyclization resulted in azepine ring formation.

preparation of 2 β oxo 2 oxazolines and Thiazolines by reaction of enamines with 2 chloroethyl iso thio cyanates
Synthesis, 1993Co-Authors: Florence Castan, Frederic Denonne, Dennis BiggAbstract:Pyrrolidino enamines react with 2-chloroethyl iso(thio)cyanate to give, after hydrolysis, 2-(beta-oxo)-2-oxazolines and Thiazolines in fair to good overall yield.
