The preparation of non-substituted amidrazones

Autor: W. J. van der Burg

Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 74:257-262

The synthesis of a number of non-substituted amidrazones is described. The compounds were prepared in order to test them for possible growth-inhibiting properties against Mycobacterium tuberculosis. They were characterised by their N1-benzylidene der

Attempts to transform potential intermediates prepared earlier into 18-oxygenated steroids are described. One of the routes lead to the substiuted D-homoandrostane derivative (XXIX) mentioned in the title.

Non-destructive testing is important in the search for seed characteristics that relate to quality. It provides a means for consecutive testing on a seed by seed basis. If the tests are fast and can be automated they can form the basis for rapid new
