“…Interestingly,t he reaction of unsymmetrical b-diketone 4m with 2a resulted in ar egioisomeric mixture of 5ma and 5mb in 75 %y ield (5ma/5mb= 5:1; Table 3, entry 13). Moreover, sub-strates containing naphthalene, pyridine, furan,a nd thiophene moieties were also suitable for this reaction, affording the corresponding products in moderate to good yields ( Table 3, entries [14][15][16][17]. Finally,t of urthere xtend the reactions cope, 3oxo-3-arylpropanenitriles, b-keto sulfone, and diethyl( 2-oxo-2phenylethyl)phosphonate were also investigated under the optimal conditions.…”
