relied on the availability of diverse starting materials prepared by traditional chemical synthesis methods. Here the synthesis of all acyclic dicarbonyl compounds and α-aminoketones used in the prior prebiotic model studies is described. There are five sets of acyclic dicarbonyl compounds including (i) β-ketoesters bearing diverse 4-substituents, (ii) levulinic acid derivatives bearing selected 5-substituents

antibacterial activity was determined as the minimum inhibitory concentration against a range of Gram-positive and Gram-negative organisms using a standard Agar dilution procedure. Compounds possessing an acid functionality directly on, or close to, the ring were found to be of greatly decreased potency, while increasing lipophilicity with greater chain length led to increased potency of these derivatives

Convenient syntheses of 1H-pyrazin-2-ones and 2-aminopyrazines are described. By coupling Boc-protected amino acids with α-amino ketones or with amino alcohols and subsequent oxidation, 1H-pyrazin-2-ones were obtained. Transformation into the corresponding pyrazine triflates and substitution with primary or secondary amines led to 2-aminopyrazines. Since these syntheses take advantage of the use of readily available starting materials (e.g., amino acids, aminoalcohols and amines) a variety of the entitled structures can be obtained in few, high yielding steps.
