The complexation between D-threitol (1) and 2,4,6-[3,4-bis(bromomethyl)phenyl]boroxin (2) selectively afforded l>-threitol-l,3:2,4-bis [-3,4-(bisbromomethyl)phenylboro~tte] (4) including two six-membered rings, whose structure was identified by means of NMR and IR spectroscopy and X-ray crystallogra
A novel seven-membered ring was unexpectedly isolated from the coupling of dithiodiglycolic acid with 2.2 equiv. of N-hydroxysuccinimide, followed by addition of 0.25 equiv. of methyl (4-aminomethyl)benzoate hydrochloride (2) in the presence of 2 equiv. of triethylamine.
