    摘要: A compound having the structure:
    wherein n is an integer from 1-5; each of R 1 and R 2 independently is optionally substituted C 1 -C 6 alkyl; each of W and X is independently hydrogen or C 1 -C 6 alkyl; Y is O, S or NR 3 where R 3 is hydrogen, C 1 -C 6 alkyl or a protective group; and Z is a CD ring structure of the formula
    a steroid ring structure of the formula
    or a vitamin D structure of the formula
    wherein each of the structures of Z optionally have one or more protected or unprotected substituents and/or one or more protective groups, and wherein any ring of the structure of Z may optionally have one or more unsaturated bonds.

    摘要: A process for preparing a compound having structure (I) wherein n is an integer from 1-5; each of R1 and R2 independently is optionally substituted C1-C6 alkyl; each of W and X is independently hydrogen or C1-C6 alkyl; Y is O, S or NR3 where R3 is hydrogen, C1-C6 alkyl or a protective group; and Z is a CD ring structure, a steroid structure, or a vitamin D structure, each of which optionally has one or more protected or unprotected substituents and/or one or more protective groups. This process comprises reacting a compound having structure (IV) wherein W, X, Y and Z are as defined above, in the presence of a base, with a compound having structure (V) or (V') wherein n, R1 and R2 are as defined above, and E is an eliminating group.
