PRODUCTION AND PROPERTIES OF 1,4-CYCLIC ADDUCTS OF STEROID 5,7-DIENES WITH 3,6-PYRIDAZINEDIONE AND 1,4-PHTHALAZINEDIONE

1,3-Phthalazinedione and 3,6-pyridazinedione, obtained by the action of lead tetraacetate or manganese dioxide on phthalohydrazide and of lead tetraacetate on malehydrazide, form 1,4-cyclic adducts in reaction with steroid 5,7-dienes; the reaction is promoted by the presence of aliphatic alcohols.The initial dienes can be regenerated from the synthesized cyclic adducts by reductive cleavage with complex metal hydrides or by electrochemical reduction.In addition to ergosterol, the action of a water-alcohol solution of alkali on the cyclic adduct of ergosterol with 1,4-phthalazinedione gives a salt-like compound, which is converted into 9(11)-dehydroergosterol and phthalohydrazide by the action of acids.
