20090177001 | NOVEL PROCESS AND INTERMEDIATES - The present invention relates to a process for the preparation of steroidal 17β-carboxylic thioates. More particularly the present invention relates to a convenient and efficient synthesis of steroidal 17β-carboxylic thioates, such as fluticasone propionate I, using soluble mixed fluorides to introduce fluorine by displacing an appropriate leaving group X in compounds II resulting in selective and controlled fluorination. The present invention also relates to intermediates II and their preparation. | 07-09-2009 |
20090275767 | PROCESS FOR SYNTHESIS OF ANDROSTANE 17-BETA CARBOTHIOIC ACID AND RELATIVE COMPOUNDS THEREOF - A process for synthesis of androstane 17-β carbothioic acid is provided. The process includes mixing an androstane 17-β carboxylic acid and a coupling reagent, and adding an alkanethioic acid to form an androstane 17-β carbothioic acid, wherein the androstane 17-β carbothioic acid has the formula (I): | 11-05-2009 |
20110118488 | PROCESS FOR OBTAINING 6-ALKYLIDENANDROST-1, 4-DIENE-3-ONE - 6-alkylidenandrost-1,4-dien-3-ones of general formula (I), wherein R is H o alkyl; R | 05-19-2011 |
20110124894 | METHOD FOR OBTAINING LONG CHAIN ALIPHATIC ALCOHOLS AND FATTY ACIDS FROM SUGAR CANE MUD AND RELATED WAX ESTERS - Methods are provided for the extraction of wax esters from sugar cane mud, isolation of the wax, saponification of the wax, either after isolation or in an intermediate un-isolated form to provide higher primary aliphatic alcohols (HPAA's) and fatty acids having nutritional and medicinal uses. The solid waste resulting from the process can be disposed of or utilized as a soil substitute following an optional water wash. Additionally, methods are provided for providing modified forms of the sugar cane mud or cachaza having reduced volumes and/or water content that require less storage space and capable of being stored for long periods of time with little or no biological degradation. | 05-26-2011 |
