Direct olefination of benzaldehydes into 1,3-diarylpropenes via a copper-catalyzed heterodomino Knoevenagel-decarboxylation-Csp(3)-H activation sequence.
Copper-catalyzed direct olefination of benzaldehydes into 1,3-diarylpropenes by a novel domino Knoevenagel-decarboxylation-Csp(3)-H activation sequence is reported. This method provides a concise and effective route toward the synthesis of unsymmetrical 1,3-diarylpropene derivatives.
متن کاملH R Csp
A large number of interesting combinatorial optimization problems like M3SAT, MC fall under the class of constraint satisfaction problems. Recent work by one of the authors [34] identifies a semidefinite programming relaxation that yields the optimal approximation ratio for every CSP, under the Unique Games Conjecture. In this work, we present an efficient rounding scheme that achieves th...
متن کاملManganese-catalyzed late-stage aliphatic C-H azidation.
We report a manganese-catalyzed aliphatic C-H azidation reaction that can efficiently convert secondary, tertiary, and benzylic C-H bonds to the corresponding azides. The method utilizes aqueous sodium azide solution as the azide source and can be performed under air. Besides its operational simplicity, the potential of this method for late-stage functionalization has been demonstrated by succe...
متن کاملCopper-Catalyzed Ring-Expansion/Thiolactonization via Azidation of Internal Olefinic C–H Bond under Mild Conditions
A copper(I)-catalyzed, (diacetoxyiodo)benzene [PhI(OAc)2]-mediated ring-expansion/thiolactonization of a-oxo ketene dithioacetals was efficiently realized via azidation of the internal olefinic C@H bond with sodium azide under mild conditions. Sequential amination, ring-expansion rearrangement, and thiolactonization occurred to form aminated thiolactones in the presence of acetic anhydride as t...
