摘要:
A process for the preparation of a compound of the formula ##STR1## comprising reacting 1R, cis 2,2-dimethyl 3-(2-oxopropyl)-cyclopropane-1-carboxylic acid with an alkali metal, alkaline-earth metal or magnesium hypohalite, and oxidizing the 1R, cis 2,2-dimethyl 3-(hydroxy-carboxy-methyl)-cyclopropane-1-carboxylic acid or its salt or lactonic form thereof thus obtained with an oxidizing agent to obtain the compound of formula I and novel intermediates.
摘要:
The present invention is directed to a novel process for preparing heteroaryl and unsaturated heterocycloalkylmagnesium reagents that are useful in the synthesis of a variety of pharmaceuticals, in particular certain cysteine protease inhibitors.
摘要:
The invention relates to a novel process for preparing compounds of the formula (IV) or (I): from the racemic alkoxyfuranone of the formula (II): R1 and R2 being as defined in the description, to the novel compounds of the formula (IV) as well as to the intermediate compounds of this process, and to the use of the compounds of the formula (IV) or (I) in the process for the synthesis of compounds which inhibit interleukin-1beta converting enzyme.
摘要:
The invention relates to novel crystalline forms of 3-beta-amino-17-methylene-androstane-6-alpha,7-beta-diol hydrochloride, referred to as form A, form B and form C, a method for preparing same, the use thereof as a drug, and pharmaceutical compositions containing same.
摘要:
A subject of the invention is a process for the preparation of the compounds of formula (I): R being as defined in the description as well as their salts, the intermediates, the use of the dihydrochloride as a medicament and the pharmaceutical compositions containing them.
摘要:
A subject of the invention is a process for the preparation of the compounds of formula (I): R being as defined in the description as well as their salts, the intermediates, the use of the dihydrochloride as a medicament and the pharmaceutical compositions containing them. The process for preparing formula (I) leads to greater than 50% yield of isomer A, and its intended use, e.g. as an antifungal medicament.
