A Novel o-Iminophenyl Anion Route to Heterocycles and Ortho-Substituted Anilines
摘要:
Ring opening of lithio derivatives of N-(alpha-alkoxyalkyl)benzotriazoles 9 and 22 and subsequent extrusion of nitrogen at -78 degrees C gave novel o-iminophenyl anions which enable synthetically useful preparations of ortho-substituted anilines (19 and 25) and of benzoheterocycles (14, 20, 21, 24, and 26).
Reactions of 1-(.alpha.-alkoxyalkyl)- and 1-(.alpha.-(aryloxy)alkyl)benzotriazoles with the Grignard reagents. A new and versatile method for the preparation of ethers
