ABSTRACT:
A method for synthesizing a cardenolide or isocardenolide by subjecting an .alpha.,.beta.-unsaturated steroidal 17-ketone to a double bond shift and hydrogenation to produce a (C/D cisoid) ketone which is treated with an organometallic reagent to yield a tertiary alcohol and the acidifying said alcohol to produce said cardenolide or isocardenolide is shown. The invention also relates to organometallic reagents particularly useful in such method.
