Suzuki−Miyaura and Sonogashira Coupling of 6-Chloropurines and -Nucleosides in Water
摘要:
A general protocol is reported for the efficient Suzuki-Miyaura and the copper-free Sonogashira coupling of unprotected 6-chloropurines and unprotected beta-D-ribofuranosyl-6-chloropurine in water or in water/n-butanol utilizing Na2PdCl4 and a disulfonated and highly water-soluble fluorenylphosphine (cataCXium F sulk).
