A method for the synthesis of 3a-aryl-substituted cyclopenta[1,2-b]furan derivatives

An alternative method for the synthesis of cyclopenta[1,2-b]furan (CPF) derivatives, which show promise as chiral resolving agents, was developed. Various CPF derivatives, aryl-substituted at the 3a-position, can be synthesized via Suzuki-Miyaura coupling reaction. Georg Thieme Verlag Stuttgart.

Gold catalyzed Heck-coupling of arenediazonium o-benzenedisulfonimides

Diazonium salts, and precisely arenediazonium o-benzenedisulfonimides, have been used for the first time as efficient electrophilic partners in gold catalyzed Heck-coupling reactions. The synthetic protocol was general, easy and gave the target products in satisfactory yields. Mechanistic insights revealed the fundamental roles of the o-benzenedisulfonimide anion as an electron transfer agent thath promotes a radical pathway that does not require the presence of photocatalysts or external oxidants.
