Laha, Joydev K.; Bhimpuria, Rohan A.; Mule, Gajanan B. published the artcile< Site-Selective Oxidative C4 Alkenylation of (NH)-Pyrroles Bearing an Electron-Withdrawing C2 Group>, Formula: C8H9NO3, the main research area is pyrrole oxidative alkenylation.
A regioselective method for the oxidative C-H alkenylation of free (NH)-pyrroles with various activated and unactivated alkenes to afford 4-alkenylated (NH)-pyrroles in good to excellent yields was explored. The key features that distinguish this method from those reported in the current literature include: 1) the first report of the oxidative C4 alkenylation of (NH)-pyrroles, 2) utilization of neutral conditions, 3) C2-substituent-controlled oxidative C4 alkenylation irresp. of the nature of the free (NH)-pyrroles or N-protected pyrroles used, 4) scope of using both electron-deficient mono- and disubstituted alkenes and styrenes, and 5) synthesis of novel, enantiomerically pure 4-alkenyl-α-methyl-N-benzylpyrroles bearing a stereocenter. An important application of this process to the synthesis of indoles through tandem C4/C5 double alkenylation followed by electrothermal cyclization was also examined
