Add to ORKGElectrophile-induced ether transfer reactions of alkoxymethyl ether protected homoallylic alcohols with cyanide quench provide cyanoether adducts in high yield and excellent 1,3-syn-stereoselectivity. Subsequent base-mediated cyclization then provides the corresponding 2,4,6-trisubstituted cyano-tetrahydropyran. © 2007 The Japan Institute of Heterocyclic Chemistry
