The invention comprises benzoquinolizines of the general formula: <FORM:0845098/IV(b)/1> wherein R1, R2 and R3 represent alkoxy groups that are optionally present (any two of which may be combined as an alkylenedioxy group) and their preparation by hydrolysing and decarboxylating compounds of the general formula: <FORM:0845098/IV(b)/2> preferably by heating with aqueous mineral acids. Examples detail the preparation of 9-methoxy-, 9, 10-dimethoxy-, 9, 10-methylene-dioxy, and 9, 10, 11-trimethoxy- 2-oxo- 1, 2, 3, 4, 6, 7-hexahydro-11bH-benzo-[a]-quinolizine.
