New Process for the Preparation of Methyl Carbonates
摘要:
graphicThe methyl carbonate of HOBt was developed for the conversion of alcohols to carbonates. This method is superior to the use of methyl chloroformate or methyl pyrocarbonate, especially with more hindered alcohols. The reagent is a stable solid that is easily prepared on a multigram scale.
This paper will describe an approach to the synthesis of eplerenone, which is being marketed for the treatment of hypertension. The synthesis begins with DHEA available from wild yams and uses a combination of microbiological and chemical transformations to build eplerenone.
This invention relates to processes for the preparation of novel 7-carboxy substituted steroid compounds of Formula I,
