Abstract

Electron ionization (EI) and liquid secondary ionization mass spectra (LSIMS) of 30 coelenterazine analogues were examined by use of linked scanning at constant B/E and the fragmentation rules upon EI and LSIMS have been established. On the basis of these results the structures of intermediates in the chemiluminescence of these compounds have been deduced as monooxygenated compounds and the possible mechanisms of chemiluinescence of these compounds are discussed.

On the basis of the results LSIMS under chemiluminescence conditions, the oxygenated ions of coelenterate luciferin analogues were observed, whose structures have been deduced as A, B, and C.

    Thus a 1:2 mixture 14·HCl:16 in ethanol was heated at 80 °C for 4 h in an MW oven (Scheme 4); compounds 18a and 18b are now recovered in about 60% and 30% yield. The same protocol applied also readily to the synthesis of the known imidazopyrazinones 17a,b [31,33] (Scheme 4). Unfortunately, we were unable to identify any product from the reaction of aminopyrazine 14a with the α-ketoaldoxime 7a derived from ibuprofen, using a number of experimental conditions (14a·HCl, EtOH, 80 °C, 18 h; dioxane-EtOH, 85 °C, 24 h; dioxane-H2O, 100 °C, 70 h; dioxane-H2O + 2 equiv.
