Vinod, Thottumkara K.,Hart, Harold
, p. 5630 - 5640 (2007/10/02)
Two approaches to the synthesis of vaulted cappedophanes 3v are described.In the first, the walls and ceiling were prefabricated as in tetrathiol 5 (10a and 10b, Scheme II, are specific examples), which was then coupled with a m-terphenyl tetrabromide suc
