An I2-promoted strategy has been developed for the synthesis of thiazol-2(3H)-onederivatives from 1,3-diketones with potassium thiocyanate. This [3+2] cyclization reaction involves C−S and C−N bond formation and exhibits good functional group tolerance. A series of thiazol-2(3H)-onederivatives are obtained in moderate to good yields.

parallel kinetic resolution of racemic 1,3‐disubstituted allenes by means of a rhodium‐catalyzed addition to 1,3‐diketones furnishing enantiopure allylic 1,3‐diketones is described. Mechanistic experiments demonstrate that the different allene enantiomers react in parallel to either the diastereomeric E‐ or Z‐allylic 1,3‐diketones with the same absoluteconfiguration of the newly formed stereogenic

radical cross-coupling protocol for the construction of C(sp3)-C(O) bond is described. This provides a straightforward method for synthesis of 2-carbamoyl-1,3-dicarbonyl compounds in good to excellent yields under mild conditions. Mechanistic studies confirms the generation of both carbamoyl and C(sp3)-centered radicals directly fromoxidation of C(sp3)-H bond of formamides and 1,3-dicarbonyl compounds, respectively

A new method for the rhodium-catalyzed regioselective C–C bond formation using terminal alkynes and 1,3-dicarbonyl compounds to achieve valuable branched α-allylated 1,3-dicarbonyl products is reported. With a Rh(I)/DPEphos/p-CF3-benzoic acid as the catalyst system, the desired products can be obtained in good to excellent yields and with perfect regioselectivity. A broad range of functional groups
