(Elsevier, 1967)
Although microbiological methods of introducing oxygen at C-11 of the steroid molecule are effective, it is obvious that purely synthetic way of producing cortisone and its analogs from bile acids or hecogenin have never ...

(Elsevier, 1967)
A number of selective reductions using borane end metal borohydrides has been described. In our studies of hydroboration of steroid conjugated ketones under different conditions and with different solvents we have found ...
The conversion of unbranched primary alkyl and arylalkyl amines to nitriles by means of lead tetraacetate
(Elsevier, 1965)
The only amino compounds oxidized so far with lead tetroacetate were primary aromatic amines, which gave mainly the corresponding azo compounds(1), and some tertiary aryldialkyl amines, which in glacial acetic acid in the ...
