    摘要: Pregnane derivatives represented by general formula (I) (wherein A1 represents a hydrogen atom or a hydroxy group, A2 represents a substituent such as a hydroxy group when A1 represents a hydrogen atom, or A2 represents a hydrogen atom when A1 represents a hydroxy group, or A1 and A2 are combined together to form an oxo group; D1 represents a substituent such as a hydroxy group, and D2 represents a hydrogen atom, or D1 and D2 are combined together to form an epoxy group or a single bond; D3, D5 and D7 each represents a hydrogen atom, D4 represents a hydroxy group, and D6 represents a substituent such as a hydroxy group, or D3 and D4 may be combined together to form an epoxy group or a single bond, or D4 and D5 may be combined together to form a single bond, D5 and D6 may be combined together to form an epoxy group or a single bond, or D6 and D7 may be combined together to form a single bond; and X1 and X2 each represents a lower alkoxy group or, when combined together, they represent a lower alkylenedioxy or oxo group) and a process for their preparation. The pregnane derivatives are useful as intermediates for synthesizing vitamin D3 having a hydroxy group in the 1alpha-position.

    摘要: Steroid compounds represented by general formulae (I), (II) or (III), wherein R 1 and R 2 each represents a hydrogen atom or a hydroxyprotecting group, R represents -CH 2 -X, a carboxyl group or a protected carboxyl group, X represents a substituent such as a hydroxy group, A 1 represents an aryl group, a lower alkyl group or an aralkyl group, and Z 1 , Z 2 , Z 3 and Z 4 each represents a hydrogen atom, a hydroxy group or a protected hydroxy group. The steroid compounds are useful as intermediates for synthesis of vitamin D 3 derivatives having a hydroxy group in the la position.
