The incorporation of adamantylalanine and carboranylalanine at the P2 site of bortezomib is well tolerated and provided potent cell permeable proteasome inhibitors with increased off-rates compared to bortezomib. Adamantylalanine and carboranylalanin

Isonicotinamide (INA) co-crystallizes with carbamazepine (CBZ), as do nicotinamide (NA) and benzamide. The structure of CBZ−INA form II is solved from powder and is shown to be isostructural with CBZ−NA. However picolinamide (PA), despite its sim

Activation of mannuronic acid esters leads to a conformational mixture of alpha-anomeric triflates, in which the equatorial triflate ((1)C(4), chair) is formed preferentially. This unexpected intermediate clearly opposes the anomeric effect and is ma

The title solvate, C7H6O4·C2H3N, comprises two molecules, one acid and one solvent. The main molecules are arranged in layers by a two-dimensional hydrogen-bond network. In this way, channels are formed along the [100] axis, which are occupied b

Two synthetic strategies for the generation of delta-substituted pyranoid sugar amino acids (SAAs) are evaluated. The first employs chiral nonracemic tert-butane sulfinamides as key reagents. Regardless of the stereochemistry of the applied sulfinami
