1H- und 13C-n.m.r.-spektren der 1,6-anhydrohexofuranosen

The 1 H-n.m.r. spectra of all eight diastereomeric 1,6-anhydrohexofuranoses were recorded for solutions in D 2 O at 270 or 300 MHz, and were interpreted first order. For the same solutions, the broad-band decoupled 13 C-n.m.r. spectra of these compounds were recorded at 67.9 or 75.5 MHz, and the 13 C-n.m.r. spectra of the triacetates in ( 2 H)chloroform were tentatively interpreted.
