高邻苯二甲酸酐 | homophthalic anhydride | 703-59-3 | C9H6O3 | 162.145 |
A number of novel isoquinoline-1,3-dione derivatives have been synthesised using the readily obtainable anhydride formed from the Stobbe-type condensation of diethyl homophthalate with p-anisaldehyde. Primary amines form amides at the C-1 carbonyl group; recyclisation gives 4-(4-methoxybenzylidene)isoquinoline-1,3-diones.
