Synthesis and properties of 8-aza- 17-thia-d-homogona-12,17a-diones [Elektronische Daten] [M. Budnikova, O. Gulyakevich, T. Zheldakova, A. Mikhal'chuk, D. Rubinov] 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.
