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.

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 regioselective dearomative aza-(3 + 2) cycloaddition reaction of substituted indoles with α-halohydroxamates has been developed. This transformation provides rapid access to highly functionalized pyrroloindolines that are represented in large number of bioactive compounds. The natural product, physostigmine, has been concisely synthesized utilizing this method.
Highly diastereoselective oxa-[3+3] cyclization with C,N-cyclic azomethine imines <i>via</i> the copper-catalyzed aerobic oxygenated CC bond of indoles
Herein, a copper-catalyzedhighlydiastereoselective aerobic oxygenated [3+3] cyclization of 3-substituted indoles with C,N-cyclic azomethine imines using oxygen as the sole oxidant under mild conditions has been developed. This protocol provides a simple and convenient approach for constructing [2,3]-fused indoline O-heterocycles bearing two pharmaceutically intriguing parts, tetrahydroisoquinoline
