, p. 549 - 556 (2007/10/03)
Steroids with hydroxyl group in positions 2, 3, 6, 7, 17 and 20 were esterified with heptafluorobutyric anhydride. The obtained esters on treatment with lithium bromide in N,N-dimethylacetamide in the presence of pyridinium tosylate afforded the corresponding olefins in high yields.

1,4-Cycloadducts of various steroidal 5,7-dienes and 4-phenyl-1,2,4-triazoline-3,5-dione gave a separable mixture (3 : 2) of the corresponding Δ5- and Δ7-sterols in good yield when treated with lithium dissolved in refluxing ethylamine.
