| abstract |
A method for preparing 16a-methyl steroids by treating the starting compound with a methylating agent in the presence of a copper-based catalyst, followed by hydrolysis of the 16a-methylated enolate to obtain the corresponding enol, followed by exposure to an oxidizing agent to obtain the desired compound. |
