reactions to afford skeletally diverse molecules are described. The reaction involved azomethineimine formation and a cyclocondensation reaction as individual steps. The methodology provides excellent regio- and stereocontrol. Skeletal diversity was ensured by changing the electrophilic counterpart of azomethineimine. Due to its broader diversity and complexity, the DOS methodology is likely to benefit
A general and efficient approach to 2H-indazoles and 1H-pyrazoles through copper-catalyzed intramolecular N–N bond formation under mild conditions

A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method.

Synthesis of pyrazolo[1,5-c]quinazolines from four easily available precursors is presented through a one-pot tricyclic Pd(II)/Ag(I) relay catalysis. The bimetallic relay cascade forges five new chemical bonds by concatenating six discrete chemical steps. The relay catalysis enables four-component assembly of pyrazolo[1,5-c]quinazolines that selectively inhibit EGFR, exhibit apoptosis through the ROS-induced

Ugi-type strategy (U-3CR) for the synthesis of a wide variety of α-amino amidines has been developed by using silica gel as promoter, and a novel access to amidino substituted indazoles in a regioselective manner is presented via iron(III) catalyzed post Ugi cyclization strategy. This method allows an easy construction of amidino substituted indazoles in good yields with broad substrate scope starting from
