Benzonitrile oxide cycloadds preferentially anti to the substituents of cis-3,5-di-X-cyclopentenes, where X= OMe, OAc, OCOPh, Br, Cl, and OH.Higher stereoselectivities are found for cis-2,5-di-X-2,5-dihydrofurans.The origins of these selectivities, and contrasts with acyclic and cyclobutene analogs, are described.
