Synthesis of 2-Aminobenzoxazoles Using Tetramethyl Orthocarbonate or 1,1-Dichlorodiphenoxymethane

[摘要]：The synthesis of 2-aminobenzoxazoles can be readily achieved by two versatile, one-pot procedures utilizing commercially available tetramethyl orthocarbonate or 1,1-dichlorodiphenoxymethane, an amine, and an optionally substituted 2-aminophenol The reactions were conducted under mild conditions and provided 2-aminobenzoxazoles in modest to excellent yields A variety of amines and substituted 2-aminophenols were used to investigate the scope of the reactions
