- Syntheses of Reactive Fluorescent Stains Derived from 5(2)-Aryl-2(5)-(4-pyridyl)oxazoles and Bifunctionally Reactive Linkers
-
Several bifunctionally reactive linkers containing halide or sulfonate ester groups were prepared.The linkers were used to quaternize 5-(4-methoxyphenyl)-2-(4-pyridyl)oxazole and 2-(6-chromanyl)-5-(4-pyridyl)oxazole to produce fluorescent stains that contained a reactive group such as an isothiocyanate, an N-hydroxysuccinimidyl ester, a maleimide, or an oxirane.The stains were derivatized with either 1-propyl-amine, 1-propanethiol, or piperidine, as appropriate, to help in characteriazation.The stains may serve as more photostable alternatives to fluoresceins or coumarins.

- Synthesis of Novel Tetraazapentalene Derivatives with Fused Cyclic Systems
-
Tetraazapentalene derivatives (R=CH3, CH2=CHCH2) reacted with ω-halogenoalkyl isothiocyanates to give novel tetraazapentalene derivatives with fused cyclic systems in good yields.
