| Abstract: | A novel class of β -formylsteroidal enamides has been prepared from 16-dehydropregnenolone-20-oxime. Reaction of these enamides with Vilsmeier reagent affords steroidal geminal dichlorides in good yields. Reaction of the corresponding C-16 formylidenemalononitrile derivative with chloromethyleneiminium salt, however, leads to a ring-D fused pyridosteroid. |
