Dialkyl pentacyclo2,5.03,8.04,7>octane-1,4-dicarboxylates (where alkyl is methyl, iso-propyl, 2-fluoro-2,2-dinitroethyl, or 2,2,2-trinitroethyl) were prepared in high yields by O-alkylation of 1,4-cubanedicarboxylic acid with the corresponding monoalkyl sulfates. - Keywords: pentacyclo2,5.03,8.04,7>octane-1,4-dicarboxylic acid, esters; monoalkyl sulfates, O-alkylation.

An effective methods of esterification of 1,4-cubanedicarboxylic acid with alkylsulfuric acids is proposed.The derivatives of alkanols with substantially different pKa values are obtained in high yields.Molecular structures of the esters obtained are confirmed by various methods.The X-ray study showed a remarcable effect of the nature of an alkyl radical on the geometry of the cubane core. - Key words: 1,4-cubanedicarboxylic acid, esterification, alkylsulfuric acids, X-ray method.

The highly strained cubane system is of great interest as a scaffold and rigid linker in both pharmaceutical and materials chemistry. A straightforward approach is reported for the scale-up of a [2+2] photocycloaddition step using convenient home-made flow photoreactors to access dimethyl 1,4-cubanedicarboxylate on decagram-scale in 33-40% yield over 8 steps. The process is demonstrated on 3.4 g·h -1input with 30 minutes residence time, enabling to reduce the process time and to avoid the use of batch photoreactors. Completion of the characterisation of the photocycloadduct and its hydrates is reported.
Structure-activity relationships of N-substituted 4-(trifluoromethoxy) benzamidines with affinity for GluN2B-containing NMDA receptors

GluN2B subtype-selective NMDA antagonists represent promising therapeutic targets for the symptomatic treatment of multiple CNS pathologies. A series of N-benzyl substituted benzamidines were synthesised and the benzyl ring was further replaced with various polycyclic moieties. Compounds were evaluated for activity at GluN2B containing NMDA receptors where analogues 9, 12, 16 and 18 were the most potent of the series, replacement of the benzyl ring with polycycles resulted in a complete loss of activity.
