Protoberberines from Reissert-Compounds VIII [1]. Oxazoloisoquinolines, New and Efficient Educts for the Synthesis of 8-Oxoprotoberberines
Certain benzylated oxazoloisoquinolinones readily available from Reissert compounds provided an efficient access to 8-oxoprotoberberines in three steps. A series of these new precursors as well as several oxoprotoberberines were prepared and the scope and limitation of this procedure were investigated.

Novel Cycloadditions of Isoquinoline Reissert Salts
Isoquinoline Reissert salts 5 partake in novel cycloadditions with acetylenic aldehydes 11 giving novel oxazoles 14 which have been characterised by X-ray crystallography.In contrast, closely related phthalazine Reissert salts 6 and phenanthridine Reissert salts 15 react by an alternative pathway giving pyrrolophthalazines 12 and pyrrolophenanthridines 16 respectively.

REISSERT COMPOUND STUDIES LXIII: PREPARATION OF REISSERT COMPOUNDS USING DIETHYLALUMINIUM CYANIDE
Reissert compounds and analogs were synthesized from the reaction of acid halide, heterocyclic base and diethylaluminium cyanide.This new method of Reissert compound synthesis gave yields comparable to other synthetic routes.
