โœฆ Synopsis

A new method for generating nucleoside anomeric radicals utilizing radical 1,5translocation is developed. Two kinds of ฮฒ-halovinyl groups at the C6-position of uracil nucleosides are found to be a good radical source. The 5-endo-trig cyclization of the generated nucleoside radicals give spiro nucleosides, e.g. (IV),

Radical Sequential Processes Promoted by 1,5-Radical Translocation Reaction: Formation and (3 + 2) Annulation of Alkenesulfanyl Radicals. -Alkenylsulfanyl radicals can be generated by radical addition of 2-substituted ethanethiols such as (I) to alkynes. These species can undergo 1,5-radical transl
