Dn. Rele et al., SYNTHESIS, DOUBLE MICHAEL-REACTION AND ANTIMICROBIAL ACTIVITY OF CROSS-CONJUGATED ENYONE, Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 35(5), 1996, pp. 431-436
Synthesis of the enyones 6(a-c) has been carried out by catalyzing the
reactions with CeCl3. Phase transfer catalyzed double Michael additio
n reactions of the enyone 6a have also been investigated. The bisannul
ation could be enforced through the agency of the Lindlar's catalyst.
The syntheses of a substituted cyclohexenone 11 and a spiro trione 13
are also described. In addition, antimicrobial activity of all the eny
ones 6 and the bisbenzalacetone 14 have been reported.
