Abstract
This invention relates to a novel carbamoylation method for the preparation of steroid phenolic N-disubstituted carbamate esters, and novel compounds in said method. Phenolic carbamate esters are useful for various purposes, for instance as pharmaceuticals, e.g. antitumor agents, as biocides, e.g. pesticides, and intermediates for preparing such useful compounds.
