Synthesis and characterisation of novel 4-chloro-16E-benzylidene steroidal derivatives.

Using androstenedione as the starting material, we have synthesised 11 novel 4-chloro-16-(E)-benzylidene androst-1,4-diene-3,17-dione derivatives. All the final products are novel and were identified by ¹H NMR, 13C NMR and HRMS spectrometry. [ABSTRACT FROM AUTHOR]
