The alpha-effect can be used in the acceleration of the Diels-Alder reaction between a series of dienes and electron deficient dienophiles using iminiumion catalysis, providing a novel molecular scaffold capable of performing this class of catalytic process.

N′-Propylhydrazide analogs of hydroxamic inhibitors of histone deacetylases (HDACs), including tubastatin A, vorinostat and belinostat, were synthesized. All prepared compounds inhibited HDAC1/2/3, but not HDAC6, except for one hydrazide analog of HDAC4/5/7 inhibitor that was completely inactive. A novel 4-substituted derivative of N′-propylbenzohydrazide with extremely high anti-HCV activity was discovered.
