    • The invention relates to new pregnene derivatives of the general formula (I), ##STR1## wherein R.sup.1 stands for a C.sub.1-4 alkyl group;R.sup.2 stands for a hydrogen atom or a C.sub.2-4 alkanoyl group;R.sup.3 stands for a hydrogen atom, a hydroxyl group or a C.sub.2-4 alkanoyloxy group;A represents a ring of the general formula (1) ##STR2## or a ring of the general formula (2), ##STR3## wherein R.sup.4 means a hydrogen atom or a methyl group;R.sup.5 stands for a hydroxyl group, a C.sub.2-4 alkanoyloxy group or a C.sub.1-3 alkoxy group;R.sup.6 means a hydroxyl group, a C.sub.2-4 alkanoyloxy group, a C.sub.1-3 alkoxy group, an oxo group or a C.sub.2-3 alkylenedithio group; the dotted line optionally represents one or more additional valence bonds, with the proviso that, when the dotted line between C.sub.9 and C.sub.11 represents an additional valence bond, then R.sup.3 stands for a hydrogen atom; and the wavy line shows that the given substituent can be bound to the carbon atom in two alternative spatial arrangements,as well as to their stereoisomers and the mixture of these stereoisomers.The compounds of the general formula (I) are valuable intermediates for the synthesis of known biologically active 21-hydroxyprogesterone derivatives.
    • 本发明涉及通式(I)的新孕烯衍生物,其中R1代表C1-4烷基; R2代表氢原子或C2-4烷酰基; R3代表氢原子,羟基或C2-4烷酰氧基; A表示通式(1)的环,(1)或通式(2)的环,其中R 4表示氢原子或甲基; R5代表羟基,C2-4烷酰氧基或C1-3烷氧基; R6表示羟基,C2-4烷酰氧基,C1-3烷氧基,氧代基或C2-3亚烷基二硫基; 虚线可选地表示一个或多个另外的价键,条件是当C9和C11之间的虚线表示另外的价键时,则R3代表氢原子; 并且波浪线表示给定的取代基可以以两种可选的空间排列结合于碳原子,以及它们的立体异构体和这些立体异构体的混合物。 通式(I)的化合物是合成已知生物活性的21-羟孕酮衍生物的有价值的中间体。
