Phenazine-1,6-dicarboxylate and its dimethyl ester as precursors of other phenazines in bacteria

Synthesis of Enaminones and Their Reaction with Dimethyl Acetylene Dicarboxylate

In present paper a simple procedure for the synthesis of enaminones without catalyst from 1,3-diketones that reacted with primary or secondary amines in ethanol as solvent, as well as the reaction of enaminones with unsaturated esters such as dimethyl acetylene dicarboxylate are reported.

Dimethyl 2,6,8-trimethyl-1,2-dihydroquinoline-2,4-dicarboxylate

The title compound, C(16)H(19)NO(4), the hydrogenated ring adopts a twisted conformation. In the crystal, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric R(2) (2)(10) dimers. These dimers are further connected via inter-molecular N-H⋯O hydrogen bonds, forming infinite double chains along [001].
