Two new macrocyclic oligoboronates were prepared in easy one step synt
heses from aminodialcohols and phenylboronic acid. Reaction of 2,6-pyr
idinedimethanol gives a tetrameric species, while 2-(salicylideneamino
)-1-hydroxyethane provides a cyclobisboronate. Both compounds are char
acterized by using X-ray structural analyses. Possible applications in
the supramolecular host-guest chemistry an discussed. (C) 1997 Elsevi
