Reaction Conditions

Reaction Steps

To a solution of trimethylsilylacetylene (0.24 mL, 1.715 mmol) in anhydrous THF (5.7 mL) at 0° C. was added a solution of n-BuLi (1.07 mL, 1.715 mmol) 1.6 M in hexanes and the resulting mixture was stirred for 2 h. Subsequently, the mixture was cooled to −78° C. and a solution of 3α-(t-butyidiphenylsilyloxy)-5α-androstan-17β-carboxaldehyde (310 mg, 0.57 mmol) in THF (5.7 mL) was added and the mixture was stirred at this temperature for 3 h. Quenching of the reaction by the addition of NH4Cl was followed by extraction with ethyl acetate.
