The present invention discloses compound 2β,3α,5α-trihydroxy-androst-6-one, having the structure of formula (I). The present invention also discloses a plurality of methods for preparing the compound and a use of the compound.
摘要:
The invention relates to 3α-hydroxy, 17-(un)substituted derivatives of the androstane series and 3α-hydroxy, 21-substituted derivatives of the pregnane series. These derivatives are capable of acting at a recently identified site on the GRC, thereby modulating brain excitability in a manner that will alleviate stress, anxiety, insomnia, mood disorders that are amenable to GRC-active agents (such as depression) and seizure activity. The steroid derivatives of this invention are those having general structural formula (I), wherein R, R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are further defined herein and the dotted lines are single or double bonds. The structure includes androstanes pregnanes (R4 = methyl), 19-norandrostanes, and norpregnanes (R4 = H).

摘要:
The method described calls for primary and secondary alcohols to be reacted with perfluorobutane sulphonyl fluoride, or with higher homologues such as perfluorooctane sulphonyl fluoride, in the presence of 2-3 equivalents of strong organic bases and in pure organic solvents.
