Sažetak

It was confirmed that the cerebrin anhydro base from yeast (Ila) isolated according to the procedure established by Reindel et ai.2 ,a h as a C20 -structure rather than C1 s-structure as one might conclude erroneously by simple comparison of physical constants 'C/f both bases. The tetrahydrofuran structure was a lso d emonstrated by means of the IR spectroscopy. For this purpose following new compounds derived from C20 -anhydro b ase were prepared: N,0-diacetyl (lib), N,0-ditosyl (Ile), 0-acetyl-N-benzoyl (!Id) and Nphthaloyl derivative (III);· in addition, 2-hexadecyl-3 ,4-dihydroxytetrahydrofuran(IV) - a deamination product of the base was described.
