Chiral amines are an important class of organic compounds. They ubiquitous in chemistry and often serve as fundamental building blocks, versatile synthons, efficient chiral catalysts, ligands or auxiliaries asymmetric synthesis medicinal chemistry. During the past few decades, there has been remarkable progress development methods. Accordingly, synthesis, particularly catalytic enantioselective...
A family of endogenous lipids, structurally analogous to the endogenous cannabinoid, N-arachidonoyl ethanolamine (Anandamide), and called N-acyl amides have emerged as a family of biologically active compounds at TRP receptors. N-acyl amides are constructed from an acyl group and an amine via an amide bond. This same structure can be modified by changing either the fatty acid or the amide to fo...
A highly efficient and simple protocol for the synthesis of 2-amidoalkylphenols has been described. The one-pot multi-component condensation of phenols with aromatic aldehydes and amides in the presence of catalytic amount of SO3H-functionalized phthalimide (SFP) under solvent-free conditions afford the title compounds in high yields and relatively short reaction times. It is noteworthy that th...
Hydrosilylation of secondary and tertiary amides to amines is described using catalytic amounts of B(C6F5)3. The organic catalyst enables the reduction of amides with cost-efficient, non-toxic and air stable PMHS and TMDS hydrosilanes. The methodology was successfully extended to the more challenging reduction of primary amides.
A series of N-allenyl amides was prepared conveniently from N-propargyl amides in good to excellent yields via a modified procedure developed in this group. The palladium-catalyzed coupling-cyclization of these prepared N-allenyl amides in the presence of organic iodides has been developed affording the oxazoline derivatives efficiently.
A literature review has shown that the daily intakes of various N-nitroso-precursor classes in a typical European diet span five orders of magnitude. Amides in the form of protein, and guanidines in the form of creatine and creatinine, are the nitrosatable groups found most abundantly in the diet, approaching levels of 100 g/day and 1 g/day, respectively. Approximately 100 mg of primary amines ...
