A one-pot synthesis of 3, 3-Dimethyl-7, 11-diphenyl-spiro [5, 5] undecane-1, 5, 9-triones 4a-c has been achieved by the application of Michael reaction between dimedone (5,5-dimethylcyclohexane-1,3-dione) 1 and trans,trans diarylideneacetones [1,5-diaryl-1,4- pentadien-3-ones] 2a-c (a. Ar = C6H5-, b. Ar = 2-Cl-C6H4-, c. Ar = 2- CH3O- C6H4) using Lewis acid catalysts.DOI: http://dx.doi.org/10.3329/dujs.v60i1.10349  Dhaka Univ. J. Sci. 60(1): 121-124 2012 (January)

An intriguing DABCO-catalyzed and DBU-promoted one-pot synthesis of an important class of (2-hydroxyaryl)pyridine derivatives bearing a carboxylate or a nitrile group suitably placed at C3 position of the aza-ring has been achieved in acceptable chemical yields with a broad functional group tolerance. This sequential C–C/C–N bond making process proceeds through a regioselective allylic alkylation/aza-Michael reaction between MBH carbonates derived from an acrylate/acrylonitrile and N-sulfonyl ketimines as C,N-binucleophiles catalyzed by DABCO, followed by elimination of SO2 under the influence of base and subsequent aromatization in an open atmosphere.
