2,5 Diemthoxytetrahydrofuran can be converted in quantitative yield to succindialdehyde with HCL or H2SO4 in aqueous solutions without workup.
There is also a way from 1,4 - butanediol to succindialdehyde. If i remember right, there is a patent, maybe 1975, to BASF

Succinaldehyde (1,4-Butanedial)
Some physical properties of succinaldehyde and its CAS registry number are given in Table (
. To avoid spontaneous polymerization of anhydrous succinaldehyde, it is best stored as a cyclic acetal, e.g., 2,5 dimethoxytetrahydrofuran. Aqueous solutions consist mainly of the cyclic hemiacetal 2,5-dihydroxytetrahydrofuran.
Production. Succinaldehyde is prepared by various routes, e.g., reaction of chlorine with tetrahydrofuran and subsequent acid hydrolysis. Hydroformylation of acrolein acetals (mostly cyclic) yields a mixture of 2- and 3-(1,3-dioxan-2-yl)propanal. Hydrolysis of the latter forms 1,4-butanedial
Post 141 (not existing).
Due to the similar chemical properties, succinaldehyde has been replaced extensively by glutardialdehyde, diminishing its commercial importance significantly.
Uses. Succinaldehyde is used as disinfectant, biological fixative, and cross-linker in thermosetting resins.
