PROCEDURE

实验过程

1α,3β-Bis(tert-butyldimethylsilyloxy)-17-(hydroxymethyl)androsta-5,7,16-triene (200 mg, 0.367 mmol), 1-bromo-4-triethylsilyloxy-4-methyl-2-pentyne (216 mg, 0.741 mmol), sodium hydride (60% in oil, 44 mg, 1.10 mmol) 15-crown-5 (81 mg, 0.368 mmol) and tetrahydrofuran (1 ml) were subjected to reaction using a procedure similar to that of Example 5(1) (at room temperature 17 hours), worked up and purified by column chromatography (hexane:toluene=3:2) to give the titled compound (183 mg, 66%) as a pale yellow oil.
