Novel kojic acid derivatives were prepared in good yields via one-pot, four-component reaction of aromatic aldehydes with Meldrum’s acid, kojic acid, and ethanol in the presence of 1,4-diazabicyclo[2.2.2]octane immobilized on mesoporous SBA-15 as heterogeneous, nanoporous, solid-base catalyst...
Moreover 4 was converted to ethyl-2-[(4-oxo-3,4-dihydroquinazolin-2-yl)thio]acetate (10) upon reflux in ethanol containing DABCO as catalyst. The latter was reacted with aromatic aldehydes and dimethylformamide dimethylacetal (DMF-DMA) to afford a mixture of two regioselectively products ...
(Scheme 6). First, isatinN,N′-cyclic azomethine imine1reacted with MBH carbonate2in the presence of DABCO, to obtainN-alkylated products3or6. The resonance formIn-Aof3or6quickly tautomerized to the delocalized intermediateIn-Bunder DABCO. Second, pyrazolenone intermediateIn-Ccould be ...
