摘要:
The title compound has been synthesised by selenium dioxide oxidation of 2'-carboxy-2-hydroxydeoxybenzoin 3 and its structure has been confirmed spectroscopically and by X-ray crystallography. An earlier report of this compound's synthesis is shown to be erroneous. The synthesis of 3-(2-hydroxyphenyl)isoquinolin-1(2H)-ones from 2'-carboxy-2-hydroxydeoxybenzoin 3 is also described.
