Cycloaddition Route to 14α-Formylestrone and Derived 14α-Substituted Products
Bull, James R.,Thomson, Russell I.
, p. 451 - 453 (1986)
Diels-Alder addition of an ethylene equivalent to steroidal 14,16-dien-17-yl acetates provides a novel synthetic route to 14α-formylestrone, and, hence to the 14α-hydroxymethyl and 14α-methyl analogues.
Cycloaddition Route to 14,17-Ethano- and 14-Alkyl-19-norsteroids

Cycloaddition of phenyl vinyl sulphone to 14,16-dien-17-yl acetates derived from estrone proceeds regio- and stereo-selectively to give intermediates for conversion into 14,17α-ethenoestra-1,3,5(10)-triene-3,17β-diol derivatives and related ring D bridged

The search for new progesterone antagonists led to the synthesis of 14,17-bridged 11β-arylsteroids.The key step was a stereo- and regioselective cycloaddition of electron-deficient olefins to steroidal 14,16-dienes.The resulting new structures were
