Alkylation of Cyclic α,β-Unsaturated Ketones at the Double Bond

The alkylation of (+)-(1S,7aS)-1-tert-butoxy-1,2,3,6,7,7a-hexahydro-7a-methyl-5H-inden-5-one (1) at C-4 with homogeranyl bromide (2) or 3-methoxy- and 3,5-dimethoxyphenethyl tosylate or bromide (4a, b, 5a, b), resp., affords excellent yields of 3 and 6, 7

Process for the preparation of 1,3-oxygenated 8α-estratrienes and novel intermediates obtained therefrom

Novel 1,3-dialkoxy 8α-estratriene compounds of the formula STR1 WHEREIN R1 is alkyl of 1-18 carbon atoms, R2 is alkyl of 1-5 carbon atoms and Ac is alkanoyl of 1-8 carbon atoms, are obtained by a three-step synthesis from a tetrahydroindane-5-one compound.
