4,5-Benzo-3,6-dihydro-1,2-oxathiin-2-oxides (benz-fused δ-sultines) 1, were prepared by reaction of 1-hydroxy-1,3-dihydrobenzo[c]thiophen-2,2-dioxides 6 with NaBH4. Derivatives of 1 bearing alkyl substituents at position 6 are accessible from 1 upon reaction of 6 with 2RLi. 3-Aryl substituted derivatives were prepared by converting 2-benzylbenzylalcohols into their O, C dianion followed by quenching with SO2 and acidification. Benz-fused δ-sultines such as 15–17 were also prepared via the dianion route.

Aryl Substituted Derivatives

A method has been developed for the preparation of oxazolo-[5,4-b]pyridin-2(1H)-ones based on the Hoffmann reaction of 2-oxo-1,2-dihydropyridine-3-carboxamides. Hydrolysis of oxazolo[5,4-b]pyridin-2(1H)-ones and the Hoffmann reaction of 2-oxo-1,2-dihydropyridine-3-carboxamides yielded 3-aminopyridin-2(1H)-ones, including 4-aryl substituted derivatives in the series, for which effective phosphors with a quantum yield of up to 0.78 were detected. Photophysical properties of 3-aminopyridin-2(1H)-ones were studied by UV and luminescence spectroscopy methods, and the relationship between their structure and photophysical properties was revealed.
