[Synthesis of O-substituted 6-oximes of 16alpha,17alpha-cyclohexanopregn-4-en-3,6,20-triones containing a tritium label at the 1,2-position]. / Sintez O-zameshchennykh 6-oksimov 16alpha,17alpha-tsiklogeksanopregn-4-en-3,6,20-triona, soderzhashchikh tritievuiu metku v polozhenii 1,2.

ABSTRACT

6-O-(3-Methoxycarbonylpropyl)- and 6-O-(3-carboxypropyl)oximes of 16 alpha,17 alpha-cyclohexanopregn-4-ene-3,6,20-trione labeled by tritium in position 1,2 were synthesized. When using homogenous catalysts, the molar radioactivity of the resulting preparations was 1.5-1.7 PBq/mol.
