32 - 156Reaction of a Polymerization-Resistant 1,2-Dithiolane with LithiatedNitrogen Heterocycles. — A variety of lithioheterocycles cleave theS–S bond of 1,2-dithiolane (II) to give ring-opened products such as (III) or(V) in line with the carbanion mechanism proposed for the enzyme-reductiveacylations of lipoic acid. The ring-opened products from benzothiazole (IV)are decomposed by excess lithioheterocycles. — (TAZAKI, M.; HIEDA, T.;MAEDA, H.; NAGAHAMA, S.; JYO, A.; Heteroat. Chem. 9 (1998) 3, 289-294;Dep. Ind.
