An expedient synthesis of [16,16,17-2H3]-epitestosterone via a one-pot deuteration and reduction of the 17-ketone followed by epimerization of a deuterated alcohol

The 17-Oxo group in androstane derivatives was reduced by sodium in deuterium oxide to [17-2H]-17β-alcohol. The 17β-tosyloxy group of 4 was found to be stable under the conditions of the i-steroid rearrangement. The S(N)2 reaction of 17β tosyla

One-pot deuteration and reduction of ketones in the synthesis of [16,16,17-2H3]-epitestosterone

5α-Androstan-17-one and 6β-methoxy-3α,5-cyclo-5α-androstan-17-one were reduced by sodium in deuterium oxide to [16,16,17-2H3]-17β-alcohols. The 17β-tosyloxy group of [16,16,17-2H 3]-6β-methoxy-3α,5-cyclo-5α-andr
