摘要：

The stereoselective syntheses of t-3-bromo-r-2, c-9-diethyl- and r-2, c-9-diethyl-t-3-hydroxy-Delta(5)-oxonenes have been achieved by the oxidative acetalization of 2, 9-diethyl-Delta(2,5)-oxonadiene and subsequent reduction. Furthermore, the novel ring contraction of r-2, c-9-dielhyl-t-3-hydroxy-Delta(5)-oxonene to trans-2-(1-bromopropyl)-8-ethyl-Delta(4)-oxocene has been discovered.
