Abstract
A novel series of substituted 2,4,5,6-tetrahydrocyclopenta[c]pyrazoles were investigated as N-type calcium channel blockers (Cav2.2 channels), a chronic pain target. One compound was active in vivo in the rat CFA pain model.

Abstract
This article describes an efficient synthesis of a potent trehalase inhibitor, 1,1'-N-linked pseudodisaccharide 1 (consisting of two valienamines), in 14 steps with an overall yield of 12% and a first synthesis of 2 (consisting of two 2-epi-valienamines) in 15 steps with an overall yield of 24% from (-)-quinic acid. The synthesis involves a stereospecific palladium-catalyzed coupling reaction between an allylic amine and an allylic chloride as the crucial step. The acetonide blocking groups were shown to be the best hydroxyl protecting groups, compatible with the palladium-catalyzed allylic amination reaction that afforded high yields of the 1,1'-N-linked pseudodisaccharides with a minimum amount of an elimination diene side product.
