| titleOfInvention | METHOD FOR THE PRODUCTION OF UNSATURATED KETODIOLS |
| abstract | It is the object of the invention to produce new, biologically active, unsaturated ketodiols. These are of interest, for example, for medicine. According to the invention, a compound of the general formula I is reacted with a strong protic acid, for example trifluoroacetic acid, sulfuric acid, p-toluenesulfonic acid or another sulfonic acid, to form an unsaturated ketodiol of the general formula II. In general formulas I and II, R represents high 1 lower alkyl (C below 1- C below 3) and R tall 2 and R high 3 together represent a fused or optionally substituted five- or six-membered ring or a fused ring system in which the B-ring neighbors Ring is a five- or six-ring. The method is suitable inter alia for the preparation of corresponding compounds in which the rings A and B are part of a Steroigeruests. Such compounds have in the Withanolidreihe particular cytotoxic activity. |
