A NOVEL SYNTHESYS OF 2'-HYDROXY-1',3'-XYLYL CROWN ETHERS

Six novel 2'-hydroxy-1',3'-xylyl crown ethers (8a-e and 13) have been synthesized utilizing the allyl group to protect the OH function during the cyclization reaction.The macrocycles 6a-e were formed in yields of 26 to 52percent, by intermolecular reactio
