PdCl2(MeCN)(2) catalyzed intramolecular cyclization of optically pure theta-hydroxyl-alpha,beta,gamma,delta-dienylethanols 1 and 2 are described. cis and trans-2-Benzyloxymethyl-6-(1,3-pentadienyl)tetrahydropyrans 3 and 4 were produced stereoselectively with a ratio of 3:1 in excellent yield. No 1,5-chirality transfer was observed in the cyclization reaction.
