    摘要： New steroid compounds of the general formula:
    wherein X is a hydroxyl group and Y is a hydrogen atom, or X and Y, taken together, form an oxo group; each of the two R' radicals is independently a hydrogen atom, an acyl group, a silyl group, an alkoxycarbonyl group or a benzyl group, or the two R' radicals, taken together, form an alkylidene or a carbonyl group, the stereo-configuration at the 22- and 23-positions being either 22R and 23R or 22S and 23S; and R" and R''' are independently of each other a hydrogen atom or a lower alkyl group, as well as processes for preparing same. These new steroid compounds are valuable intermediates for brassinolide and its analogues useful as plant hormones.

    摘要： A process for the preparation of 2-chlorosulfonyl-4-(N-substituted sulfamyl)-chlorobenzene compounds of the general formula:
    wherein R is a hydrogen atom or a lower alkyl group, X is a 5-or 6-membered carbocyclic group which may contain an oxygen atom or atoms as ring-constituting members and may be substituted on the ring by one or more lower alkyl groups, and n is 0 or 1,
    which process comprises reacting a 2,4-dichloro- sulfonylchlorobenzene of the formula:
    with an amine of the general formula:
    wherein R, X and n are as defined above, in the presence of an acid-binding agent at a temperature of below 10°C.
