AB  - Heterocyclization of (Z)-5-(2-hydroxyethyl)-3-methyl-4-oxothiazolidines, bearing electron-withdrawing groups conjugated to an exocyclic double bond at C(2)-position, afforded under reductive conditions, cis-tetrahydroftiro[2,3-d]thiazole derivatives. The reactions of these functionalized push-pull beta-enamines occur in a stereocontrolled fashion via activated vinylogous N-methyliminium ions, which are trapped by an internal hydroxyethyl group.

AB  - A study on the regiospecificity of the base-catalyzed reaction of activated beta-oxonitriles 1 with diethyl mercaptosuccinate affording the title compounds 3 is reported. Other competitive heterocyclic products. that is 4-oxo-1.3-thiazinanes 4. derivatives of tetrahydrothiophene 5 and/or thiacyclohexane 6 which on the ggrounds of mechanistic considerations could be formed were not observed. Spectroscopic and experimental evidence. together with theoretical considerations. provides a reasonable explanation for the observed regiospecificity.
AB  - Proučavana je regiospecifičnost bazno-katalizovane reakcije aktiviranih β-oksonitrilado 1 sa dietil-estrom merkaptoćilibarne kiseline u kojoj se grade u naslovu navedena jedinjenja 3. Mogući heterociklični proizvodi 4-okso-1,3-tiazini 4, derivati tetrahidrotiofena 5 i/ili tijacikloheksana 6 koji mogu biti nagrađeni na osnovu mehanističkog razmatranja, nisu detektovani. Spektroskopski i eksperimentalni dokazi sa teorijskim obrazloženjem daju prihvatljivo objašnjenje za uočenu regiospecifičnost.
