摘要:
Disclosed is a novel composition comprising a novel bi-cyclic compound, which is expected to be pharmaceutically active, and a glyceride. The stability of the bi-cyclic compound can be improved significantly by dissolving the same in a glyceride.
摘要:
A process of preparation of Vilsmeier-Haack reagent is provided where di (trichloromethyl) carbonate reacts with N,N-dimethylformamide to form a Vilsmeier reagent, which can be used efficiently for chlorination of sucrose-6-acetate or sucrose-6-benzoate and other sucrose acylates. This process has application in the process for preparation of 1-6-Dichloro-1-6-DIDEOXY-ß-Fructofuranasyl-4-chloro-4-deoxy-galactopyranoside.
