Cyanomethylation of anthranilic acid
JOURNAL OF HETEROCYCLIC CHEMISTRY(2003)
Abstract
Anthranilic acid reacts with chloroacetonitrile and N, N-diisopropylethylamine in DMF to yield 3-imino-2,3-dihydro-4,1-benzoxazepin-5(1H)-one (1) as the only reaction product. Also known as Ashley's fluorescer, compound 1 is fluorescent and binds to calcium carbonate, including the calcium carbonate-rich antennae of Daphnia pulex, the water flea.
