Seven methylated pteridines have been synthesized by condensation of a 4-chloro-5-nitropyrimidine with a β-ketoamine (or a blocked derivative), reduction of the nitro group, and subsequent ring closure. This scheme provides a new route to dihydroxan

Starting with a chloronitrouracil, the synthesis of 1, 3, 6-trimethyllumazine has been achieved. Oxidation to the 5-oxide and subsequent rearrangement gave 6-hydroxymethyl-1, 3-dimethyllumazine. Because of the method of synthesis, the product is unco

DNA of Oncopeltus fasciatus, an organism with diffuse centromeres, has been characterized by determination of its base composition, buoyant density, thermal stability, and reassociation kinetics; renatured DNA was characterized similarly. We conclude
