| Abstract: | The use of a dicobalt hexacarbonyl protective group permitted us to carry out the stereospecific conversion of 17 -hydroxy-17 -ethynylsteroids into branched 17-R-substituted 17-ethynylsteroids (R-OH, OAc, OMe, NCS, and F).Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 3, pp. 675–681, March, 1990. |
