## Abstract Freshly prepared solutions of biliverdin dimethyl ester (**2**) in ethanol showed fluorescence maxima at 710 and 770 nm [ฮฆ~F~ = 1.1. 10^โˆ’4^ (room temperature) and 5.0 10^โˆ’4^ (77 K)]. The maxima of monoprotonated **2** at 77 K were shifted to 725 and 806 nm and the quantum yield was incr

## Abstract Biliverdin dimethyl ester (**1b;** IXฮฑ) and its XIIIฮฑ isomer **2b** have been isolated on a preparative scale after esterification of an isomeric mixture obtained by oxidation of bilirubin. Both isomers readily form solid solutions. The substitution patterns and the predominant helical

The reaction of potassium superoxide with vitamin K, and its related compounds in the presence of crown ether gave the corresponding 2,3-oxide and nhthalic acid. The oxidative cleavage of oxirane ring by superoxide ion has been observed with vitamin K, 2,3-oxide and certain epoxides.
