Polyphosphate Ester-catalysed Cyclodehydration of Monoesters of N-Substituted 3-(Indol-3'-yl)-5-methylcyclohex-4-ene-1,2-dicarboxylic Acids; Stereoselective Synthesis of Methyl 9-Methyl-6-oxo-5-tosyl-5,6,6aβ,7β,8,10aβ-hexahydroindenoindole-7α-carboxylate. X-Ray Molecular St...

The effect of the N-substituents on the polyphosphate ester-(PPE)-catalysed cyclodehydration of a monoester of N-substituted 5-methyl-3-(indol-3'-yl)cyclohex-4-ene-1,2-dicarboxylic acids (41) is presented.Stereoselective synthesis of methyl 9-methyl-6-oxo-5-tosyl-5,6,6aβ,7β,8,10aβ-hexahydroindenoindole-7α-carboxylate (2), the key synthetic intermediate for C(7)-functionalized antifertility agent yuehchukene (YCK) (1) analogues, is dexcribed.

Yuehchukene Analogues

Yuehchukene and the bisnoryuehchukenes have been synthesized by the dimerization of β-(dehydroprenyl)indole and its demethyl derivative, respectively.Several routes of preparation of the monomers were developed.These β-indolyl dienes were used in Diels-Al
