A facile synthesis of 4-(3β -methoxy-5α -androstan-17β -yl)- 3-pyrrolin-2-one
The title compound was prepared in 4 steps from 3β-methoxy-21- hydroxy-5α-pregnan-20-one (1). The required intermediate (4) was obtained using lithium enolate derived from t-butyl acetate. Interesting enough, p-tosyl chloride in pyridine quantitatively converted compound 1 into the a-chloro ketone d...
