Several synthetic approaches to neolignans with a C(8)–O–C(4′) linkage are described. Although direct introduction of a chiral aryloxy ether bond at the 8-position of protected phenylpropane derivatives was not successful, an efficient method for the synthesis of a chiral aryloxy ether bond has been developed, starting from a tartrate derivative.
