Document Type and Number:
WIPO Patent Application WO/2005/095437
Kind Code:
A1
Abstract:
Disclosed is a method for producing a steroid derivative represented by the formula (IV) below which is characterized by reacting a compound represented by the formula (I) below, a compound represented by the formula (II) below and carbon monoxide in the presence of a palladium compound and a tertiary phosphine compound represented by the formula (III) below. Also disclosed is a method for producing a steroid derivative represented by the formula (V) below which is characterized by comprising a step wherein a steroid derivative represented by the formula (IV) is obtained by reacting a compound represented by the formula (I) below, a compound represented by the formula (II) below and carbon monoxide in the presence of a palladium compound and a tertiary phosphine compound represented by the formula (III) below. (I), (II), (III), (IV), (V)
