Abstract: | 2-Alkoxypropenals react with 2-aminoethanethiol to give tautomeric mixtures of the corresponding 2-(1-alkoxyvinyl)-1,3-thiazolidines and 2-(2-alkoxy-2-propenylideneamino)ethanethiols in quantitative yield. The state of the ring-chain tautomeric equilibrium depends on the polarity and acidity of the medium and initial reactant ratio, and it does not change on raising the temperature and is only slightly affected by microwave irradiation.__________Translated from Zhurnal Organicheskoi Khimii, Vol. 41, No. 4, 2005, pp. 529–534.Original Russian Text Copyright © 2005 by Keiko, Funtikova, Stepanova, Larina. |
