several applications and as precursors for some classes of molecules. They serve as ligands' in the preparation of rhodium complex catalysts, possess interesting antifungal properties,' and are starting materials for the synthesis of 4H-chromen-4-ylidenamines.' Moreover, the stereoselective reduction of imidoyl phenols is a convenient synthetic pathway to aminophenols, another class of ligands extremely

日期:1998.12
A method has been developed for the almost exclusive C-alkylation of the 2-(1-iminoalkyl) phenols 1, important organic compounds with a range of employment, which allows the preparation of complex derivatives 4 with good yields starting from easily available materials. The operational simplicity of this method take advantages in providing a variety of alkylated 2-acyl phenols 5 by an easy hydrolysis of the 2-(1-iminoalkyl) phenols 4. (C) 1998 Elsevier Science Ltd.
