【発明の名称】15-メチル-シクロプロパノステロイドおよびその製造法

Japanese Patent JP2001525334

A

The invention relates to novel 15-methyl-cyclopropanosteroids of general formula (I), wherein R1 represents a hydrogen atom, an alkyl group, an acyl group, or a sulfamoyl group, R2 and R3 represent independently from each other a hydrogen atom or a halogen atom, R4 represents an oxo group or a hydrogen atom and a hydroxy group, and the 14,15-methylene group has either an alpha or beta configuration, wherein the 15-methyl group is in beta position when the 14,15-methylene group is arranged in alpha position and vice-versa. The invention also relates to 15 methyl-pentasteroids which are suitable as parent compounds in the production of the inventive 15-methyl-cyclopropanosteroids. The invention further relates to a method for the production of the inventive 15-methyl-cyclopropanosteroids and 15-methylpentaensteroids.
