Source of material: The title compound (alternative name: 2,4-di- 0 - b e n z y l - 3 - b e n z y I a m i n o - 3 - d e o x y - L - x y l o n o - 1 , 3 - l a c t a m ) was prepared by [2+2] cycloaddition from N,2-0-dibenzyl-glyceral- dimine (see réf. 1) with benzyloxyacetyl chloride in CH2CI2 using Et3N, followed by reaction with vinylmagnesium bromide in THF at 195 Κ (see refs. 2-5).

The Η atom at 0 ( 6 ) is rationally disordered. Therefore, it is not possible to define its location.
