β¦ Synopsis
SLmrarY
A synthetic procedure for producing [6.7-d2]trilostane is described. The synthesis was accomplished in 6 steps from androsta-4,6-dien-3,17-dione with the label being introduced by catalytic deuteration. The synthetic procedure, using [4-14Cltestosterone, gave the required ~d ~~l t r i ~o s t a n e in four steps.
