Alkyl radicals, derived from decarboxylation of carboxylic acids, add readily to phenyl vinyl sulphone and vinylphosphonium bromide. The adducts may be further converted into a variety of useful synthetic intermediates.
Oligonucleotide analogues conjugated to carrier peptides are provided. The disclosed compounds are useful for the treatment of various diseases, for example diseases where inhibition of protein expression or correction of aberrant mRNA splice products produces beneficial therapeutic effects.

Irradiation of O-acyl derivatives 1 of N-hydroxy- 2-thiopyridone with visible light in the presence of phenyl vinyl sulphone or vinyl triphenylphosphonium bromide leads to the corresponding adducts 8 and 9 which can undergo a wide variety of further transformations.
