Abstract
The 15- and 17-hydroxy derivatives of 8-aza-D-homogona-12,17a-diones were obtained by the annelation of 3,4-dihydroisoquinolines with 2-acetyl-4-hydroxycyclohexane-1,3-dione. It was shown that the reaction proceeds stereoselectively with the intermediate formation of 9,15- and 9,17-trans isomers. The probable mechanism and certain aspects of the interconnection between the structural and physicochemical characteristics of the obtained compounds are discussed.
