✦ Synopsis
The crystafs of a 4:l mixture of 6-(N-benzyl-N-iert-butoxycarbonyIamino)-2,3,6,7-tetradeoxy~ a-aberythroand -p-oL-threa-hept-2-enopyranos-4-ulose were monoclinic, space group I??,/c, with cell dimensions: a = 9.490(2), h = 21.516(S), c = 10.279(2) A, p = 115.31(l)", Z = 4. The ulose ring had a half-chair conformation deformed towards the sofa (enveiope) form. * Dedicated to Professor A. Zamojski on the occasion of his 60th birthday.
