“…This reactivity may be exploited for obtaining highly functionalized derivatives [4]. The more common application is found in preparation of 3,5-diaryl-6-carbethoxycyclohexanones, efficient synthons in building spiro compounds [5], or intermediates in the synthesis of benzisoxazoles, or carbazole derivatives [6,7], via 1,3-Michael addition of ethyl acetoacetate. Crystal structures of (8RS, 9SR)-ethyl 4-(3-bromothien-2-yl)-6-(2-furyl)-2-oxocyclohex-3-ene-1-carboxylate [8], ethyl 4-(3-bromo-2-thienyl)-2-oxo-6-phenylcyclohex -3-ene-1-carboxylate [9], (R, S)-methyl 3-methyl-5-oxo-1-phenylcyclohex-3-ene-1-carboxylate [10], rac-ethyl 3-(3-bromo-2-thienyl)-2-oxo-6-(4-propoxyphenyl)cyclohex-3-ene-1-carboxylate [11], (±)-ethyl 6-(6-methoxy-2-naphthyl)-4-(4-methylphenyl)-2-oxocyclohex-3-ene-1-carboxylate [12], ethyl 6-(6-methoxy-2-naphthyl)-2-oxo-4-(2-thienyl)cyclohex-3-ene-1-carboxylate [13], (1RS,6SR)-ethyl 4-(4-chlorophenyl)-6-(4-fluorophenyl)-2-oxocyclohex-3-ene-1-carboxylate toluene hemisolvate [14], ethyl 4-(2,4-dichlorophenyl)-6-(4-fluorophenyl)-2-oxocyclohex-3-ene-1-carboxylate [15], ethyl 4,6-bis (4-fluorophenyl)-2-oxocyclohex-3-ene-1-carboxylate [16] and methyl 4,6-bis(4-fluorophenyl)-2-oxocyclohex-3-ene-1-carboxylate [17] have been reported.…”
