Synthesis of [20,21‐13C2]‐pregnenolone
The synthesis of [20,21‐13C2]‐pregnenolone (7) from androst‐5‐en‐3β‐ol‐17‐one (1) is described. Labelled carbons were introduced by two procedures, namely, condensation of 1 with K13CN and Grignard reaction of nitrile derivative 5 with [13C]‐methylmagnesium iodide. Location of labels was confirmed b...

Sumario: | The synthesis of [20,21‐13C2]‐pregnenolone (7) from androst‐5‐en‐3β‐ol‐17‐one (1) is described. Labelled carbons were introduced by two procedures, namely, condensation of 1 with K13CN and Grignard reaction of nitrile derivative 5 with [13C]‐methylmagnesium iodide. Location of labels was confirmed by 13C‐NMR spectroscopy. Copyright © 1993 John Wiley & Sons, Ltd. |
