Abstract
A procedure for the preparation of new 17-aza-16-keto-steroid derivatives having general formulas I and Ia **(See formula)** where R represents a free or protected oxo group, preferably a ketal derivative thereof, a hydrogen atom, and an OH group or a protected derivative thereof, such as an ester, ether, or the like, R1 represents a hydrogen atom or an alcohol group of 1 to 4 carbon atoms, R 2 represents an alkoxy group, characterized in that a compound of the general formulas II or IIa **(See formula)** in which R and R2 have the same meanings as above, it is reacted with lead tetraacetate, then the product is hydrolyzed and subjected to a ring closure reaction and, if desired, the compound of general formulas I or Ia, obtained by any one of the above procedures, is hydrolyzed and/or alcoholized with an alcoholic agent containing 1 to 4 carbon atoms, and then the product is treated in a known manner.
