Enantioselective copper-catalyzed construction of aryl pyrroloindolines via an arylation-cyclization cascade
An enantioselective arylation-cyclization cascade has been accomplished using a combination of diaryliodonium salts and asymmetric copper catalysis. These mild catalytic conditions provide a new strategy for the enantioselective construction of pyrroloindolines, an important alkaloid structural motif that is commonly found among biologically active natural products.

A convenient method for the synthesis of indole-3-acetic acids
Starting from the corresponding indoles, indole-3-acetic acids were synthesized through indole-3-glyoxylic acids, followed by hydrazone formation with p-toluenesulfonhydrazide, then reduction of the hydrazones with sodium borohydride.
