SYNTHESIS OF TRITIUM LABELLED STEROID

Title:

SYNTHESIS OF TRITIUM LABELLED STEROID

Document Type and Number:

Japanese Patent JPS62281894

Kind Code:

A

Abstract:

The compounds correspond to the formula in which R is hydrogen, alkyl, tetrahydropyranyl, trityl or trimethylsilyl and R1 is hydrogen, acyl or tetrahydropyranyl. They are prepared from 17 alpha -methyl-3-methoxy-19-norpregna-1,3,5(10)-trien-20-one by a synthesis in eight, nine or ten stages depending on the meaning of R and R1. Compounds I may be used for the synthesis of steroids labelled with tritium in positions 6 and 7.
