HETEROCYCLIC SATURATED COMPOUNDS (1,3-DIOXANES AND OXAZOLIDINES) BY DIASTEREOSPECIFIC RING-CLOSURE OF THERO-2-AMINO-1-(P-NITROPHENYL)-PROPANE-1,3-DIOL .3. SOME N,N'(N'')-BIS(TRIS)-AMIDES AND SCHIFF-BASES
M. Darabantu et al., HETEROCYCLIC SATURATED COMPOUNDS (1,3-DIOXANES AND OXAZOLIDINES) BY DIASTEREOSPECIFIC RING-CLOSURE OF THERO-2-AMINO-1-(P-NITROPHENYL)-PROPANE-1,3-DIOL .3. SOME N,N'(N'')-BIS(TRIS)-AMIDES AND SCHIFF-BASES, Revue Roumaine de Chimie, 40(9), 1995, pp. 907-915
The reaction of formaldehyde-acetal of the title aminodiol with some a
cid chlorides is described when bis(tris)-N-substituted amides mere is
olated. The diastereoselective synthesis of some Schiff-bases, startin
g from cis-5-amino-4-(p-nitrophenyl)-2-(un)substituted-1 ,3-dioxanes i
s discussed. Conformational assignments are presented based on H-1-NMR
spectroscopy.
