✦ Synopsis

Reduction of a,a'-diketo selenides with a low-valent titanium reagent usually affords 3,4_dihydroxyselenolanes, from which the corresponding selenophenes are obtained by acid-catalyzed dehydration. A surprising exception is the formation of 2,4-dihydroxy-2,4-di-t_butylselenolane from bis(2-t-butyl-2-oxoethyl) selenide, the former being converted to 2,4-di-t-butylselenophene by acid treatment.

A series of selenophene derivatives 3 were synthesized as potential CHK1 inhibitors. The effects of substitution on the 4'- or 5'-position of selenophene moiety and shifting the hydroxyl group position on C6- phenolic ring of oxindole were explored.
