H. Hart et P. Rajakumar, 2'-SUBSTITUTED META-TERPHENYLS AS BUILDING-BLOCKS FOR CYCLOPHANES WITH INTRA-ANNULAR FUNCTIONALITY, Tetrahedron, 51(5), 1995, pp. 1313-1336
2'-Substituted m-terphenyls containing chloromethyl and/or thiomethyl
groups at the 4,4'' or 3,3'' positions are used as building blocks for
cyclophanes with intra-annular functionality. Syntheses are short and
yields are good. The methodology, capable of wide structural variatio
n, has been adapted to bi- and tricyclic cyclophanes.
