ABSTRACT
 
Steroidal dienones represent a class of compounds that are useful intermediates in further functionalization of the steroid nucleus. Their chemical synthesis can be problematic owing to the lack of a simplified method of preparation and  the occurrence of impurities that can be difficult to remove. We have endeavored to develop new methods of chemical synthesis of cholest-4,6-dien-3-one that would yield a product of high purity. To synthesise a variety of ring A and B modified steroids, the steroidal 4,6-dien3-ones form an important class of  compounds. In order to develop new methods for the synthesis of steroidal inhibitors of estrogen synthase(aromatase) cholest-4,6-dien3-one [1] has been used as a model compound in our synthesis work. To obtain a purified sample, the literature suggested we conduct a multi step reaction sequence. Procedures indicated that we would get a mixture of products that required extensive chromatographic purification with low yields. We made efforts to develop new synthetic approaches in this area that would make the product available for further experiments.
