2-Aminobenzaldehyde, 1-(2-aminophenyl)ethanone, and 2-aminophenyl phenyl methanone oximes 1 were reacted with aromatic aldehydes to give the corresponding 1,2-dihydroquinazoline-3-oxides 2. The latter were converted in high yields to a series of quinazoli

A new protocol for the enantioselective direct α-heteroarylation of aldehydes with isoquinoline N-oxides, via chiral enamine catalysis, has been successfully developed. High enantiomeric excesses and moderate to good yields were achieved for a variety of α-heteroarylated aldehydes.

The synthesis of 1H-indazoles is achieved from o-aminobenzoximes by the selective activation of the oxime in the presence of the amino group. The reaction occurs with a variety of substituted o-aminobenzoximes using a slight excess of methanesulfonyl chloride and triethylamine at 0-23 °C and is amenable to scale-up. The synthesis of 1 H-indazoles under these conditions is extremely mild compared with previous synthetic approaches and affords the desired compounds in good to excellent yields.
