    摘要: To provide a novel antitumor steroid compound which can be synthesized efficiently and stereoselectively by the technique of organic synthetic chemistry. A steroid derivative represented by general formula (I) or a salt thereof, wherein R represents C1-C13 alkyl; A represents hydroxyl or a group which can readily be hydrolyzed into a hydroxyl group; and X and Y represent in combination oxo or C2-C3 alkylenedioxy, or separately X represents hydroxyl, C1-C5 alkoxy or a group which can readily be hydrolyzed into a hydroxyl group, and Y represents hydrogen or C1-C5 alkoxy, provided Y represents hydrogen when X represents hydroxyl or a group which can readily be hydrolyzed into a hydroxyl group, while Y represents C1-C5 alkoxy when X represents C1-C5 alkoxy.
