- The N-substituents are transferred from the title cations to the C-atom of nitroalkane anions in highyield at 25-80°C in DMSO solution. The title cations are readily available from the appropriate pyrylium cations and primary amines of types RCH2,NH2, and RR'CHNH2, allowing a general 2-step method for the preparation of higher nitro- alkanes. Spectral properties of a variety of nitroalkanes are
The present invention provides a method for industrially producing an optically active lysine derivative useful as a pharmaceutical intermediate. More particularly, the present invention provides a production method including protecting an amino group or an amino group and carboxyl group of optically active 2-amino-6-methyl-6-nitroheptanoic acid with a protecting group, reducing a nitro group to synthesize a 6,6-dimethyl lysine derivative and reacting the 6,6-dimethyl lysine derivative with an acetic acid derivative.
The invention relates to amide-containing compounds of formula (1), and salts thereof. In some embodiments, the invention relates to inhibitors or modulators of Pim-1 and/or Pim-2, and/or Pim-3 protein kinase activity or enzyme function. In still further embodiments, the invention relates to pharmaceutical compositions comprising compounds disclosed herein, and their use in the prevention and treatment of Pim kinase related conditions and diseases, preferably cancer.
A dihydroaromatic compound is aromatized by intimately contacting it with a base selected from alkali metal, alkaline earth metal and tetralakylammonium hydroxides, alkoxides, carbonates, and bicarbonates in the presence of a hydrogen acceptor. In a preferred embodiment of the invention, the dihydroaromatic compound is a dihydronaphthalene bearing an electron-withdrawing substituent, e.g., a cyanodihydronaphthalene.
