A structurally novel compound was isolated as the main product of tandem Pechmann-dehydration between diethyl 4-hydroxy-4-methyl-2-(4′-nitrophenyl) -6-oxocyclohexane-1,3-dicarboxylate (1) and resorcinol in the presence of trifluoroacetic acid. The structu

Efficient synthetic access to highly functionalized 3,4-cyclohexane-annelated coumarins has been achieved by combining two methods. First, the important intermediates multisubstituted cyclic ?2-keto esters were prepared conveniently by condensing a variet
Catalysis by amberlyst A-21: A greener approach to 4,5,6,7-tetrahydro-1H- indazol-3(2H)-ones via construction of cyclohexanones

, p. 1076 - 1083 (2014/04/03)
The 4,5,6,7-tetrahydro-1H-indazol-3(2H)-one derivatives have been synthesized in good yields via a two-step method in a single pot. The initial step involved the construction of cyclohexanone ring from aromatic aldehydes and β-ketoester in i-PrOH using an
Indion 860 catalyzed cascade reaction: A greener approach to functionalized cyclohexanones and their novel analogues
Bhaskar Kumar,Dhananjaya,Sumanth, Ch.,Vaishaly,Botre, Gajanan,Rao, M. Srinivasa,Sekhar, K. B. Chandra,Kumar, K. Shiva,Pal, Manojit
, p. 2207 - 2210 (2013/03/14)
An Indion 860 mediated cascade reaction of β-ketoester or 1,3-diketone with alkyl/aryl/heteroaryl aldehydes afforded functionalized cyclohexanones in the open air. The catalyst can be recovered and recycled. Combining this methodology with other reactions
A facile synthesis of 4-aryl-5-alkoxycarbonyl-6-hydroxy-6-methyl-4,5,6,7-tetrahydro-3-hydroxy-2-(pyridin-2-yl)-indazoles and their nmr characterizations

, p. 537 - 554 (2008/09/20)
A series of N-pyridinyl tetrahydroindazoles have been synthesized by a convenient and regioseletive method by taking cyclic 2-ketoesters as scaffolds. An optimum reaction condition was achieved by monitoring the reaction in different reaction c
