Abstract

Reactions of 3-methyl-10-thiaisoalloxazine (2) with dihydrolipoamide and 1,4-butanedithiol (4b) gave almost exclusively redox products, whereas reactions of 2 with 1,3-propanedithiol (4c) and 1,2-ethanedithiol (4d) resulted in the concurrent occurrence of 4a,10a-cyclic addition and the redox reactions.
