DEFINITION

Classification: 548/470

(under subclass 469) Compounds wherein the ring nitrogen is bonded directly to two ring carbons of the same cyclo, which carbons are members of one cyclo only.

(1) Note. There exists a tautomeric equivalence between isoindoles and insoindolenines, as is shown below. This subclass provided for both isoindoles and isoindolenines. [figure]
