A simpleone-potprocedure for the direct reductive amination of aldehydes using lithium powder and a catalytic amount of 4,4′-di-tert-butylbiphenyl (DTBB) or a polymer supported naphthalene as reducing system is described. The direct reductive amination of a variety of aldehydes with primary amines was achieved simply by adding a mixture of the corresponding carbonyl compound and the amine, over a

A series of omegadibenzylaminoalkylamines and related compounds have been prepared and tested as inhibitors of fibrin cross-linking. This structural type was chosen in an attempt to develop noncompetitive inhibitors of fibrinoligase. By the combination of the dibenzylamino moiety at one end and the primary amino group at the other end of a polymethylene chain, the same compound could function both

This work describes the use of cheap, safe, and easy-to-handle hydrosilatrane as the reductant in direct reductive amination reactions. This efficient method enables a facile, metal-free access to secondary and tertiaryaminesfrom a wide range of aldehydes and ketones, with the synthesis of tertiaryamines requiring no additives at all. This reaction demonstrates excellent functional group tolerance
heterogeneous catalytic reductive amination of carbonylcompounds has been achieved by reactions of ammonium hydroxide and various amines with ketones and aldehydes. The process is based on the application of Raney type Ni-Al alloy in an aqueous medium. The reaction of the carbonylcompounds with the amine provided the corresponding Schiff bases that immediately underwent a reduction to provide primary
relationship of a trisubstituted sulfonamide series led to the identification of 39, which is a potent and selective CB2 receptorinverseagonist [Ki(CB2) = 5.4 nM, and Ki(CB1) = 500 nM]. The functional properties measured by cAMP assays indicated that the selected compounds were CB2 inverseagonists with high potency values (for 34, EC50 = 8.2 nM, and for 39, EC50 = 2.5 nM). Furthermore, an osteoclastogenesis
