| Abstract: | We have used annelation of 3,4-dihydroisoquinolines by 3-acyl-5,5-dimethylthiopyran-2,4-diones to obtain the corresponding 8-aza-17-thia-D-homogonanes, which are novel representatives of heterosteroids. We have studied the tautomerism of 3-acylthiopyran-2,4-diones using NMR spectroscopy and H/D-isotope exchange. We have obtained 2H-isotopomers of 3-acylthiopyran-2,4-diones.Translated from Khimiya Geterotsiklicheskikh Soedinenii, No. 10, pp. 1572–1583, October, 2004. |
