A convergent construction of [2,3]-fused indoline tetrahydropyridazines via an I2/tert-butyl hydroperoxide (TBHP) catalyzed three-component dearomative oxidative coupling of indoles, hydrazines and acetophenone was established in moderate to good yields. This protocol provides a new approach for the synthesis of these biologically interesting fused indolines.

effectively delivered from an aryl (pseudo)halide or an acid anhydride coupling partner, respectively. The developed method utilizes mild conditions and exhibits a wide substrate scope for both substituted indoles and C(sp2)-based reaction counterparts. Mechanisticstudies have shown that competitive hydrogen atom transfer (HAT) processes, which are frequently encountered in conventional methods, are not

diastereo- and enantioselective BOX/Cu(II)-catalyzed C2,C3-cyclopentannulation of indoles with donor-acceptor cyclopropanes has been developed on the basis of asymmetric formal [3 + 2] cycloaddition of indoles. This reaction provides rapid and facile access to a series of enantioenriched cyclopenta-fused indoline products and can be further extended to the construction of tetracyclic pyrroloindolines. The synthetic

A novel Pd(II) catalyzed direct oxidative Heck-Cassar-Sonogashira type alkynylation of indoles with terminal alkynes under an atmosphere of O(2) is developed. Unlike previous methods, the reaction does not require the pregeneration of indolyl halide or alkynyl halide. Furthermore, only a catalytic amount of base is required and oxygen was used as the ultimate "green" terminal oxidant.
