Abstract
A new series of macrocycles containing the diglycolyl moiety have been prepared. The compounds prepared were: 7, 9, 18, 20-tetrahydrodibenzo [b, k][1, 4, 7, 10, 13, 16] hexaoxacyclooctadecin-6, 10, 17, 21-tetraone (1), 1, 4, 7, 10, 13, 16- hexaoxacyclooctadecane-2, 6, 11, 15-tetraone (2), 8, 7, 17, 18-tetramethyl-1, 4, 7, 10, 13, 16- hexaoxa-cyclooctadecane-2, 6, 11, 15-tetraone (3) and 2, 5, 8, 15, 18, 21-hexaoxatricyclo [20, 4, 0, 0 9.14] hexacosan-3, 7, 16, 20-tetraone (4). The compound 4 has been isolated in the four diastereoisomers: trans-syn-trans 4a, trans-anti-trans 4b, cis-syn-cis 4c and cis-anti-cis 4d
