3,3-Diphenyl-2-Morpholinone Derivatives Of 2-Amino-2-Deoxy-D-Allose., Ram Babu

University of the Pacific Theses and Dissertations

A new cyclic protective group has been fused to the cis amino alcohol group of benzyl 2-amino-3,5-o-benzylidene-2-deoxyβ-D-Allopyranoside, by way of a unique rearrangements mechanism. To establish the 2-morpholinone structure, chemical studies, such as reduction and acetylation were conducted.

Comparative spectroscopic studies using ir, pmr, and C-13 nmr confirmed the assigned structures.

The 2-morpholinone ring was cleaved by mild alkaline hydrolysis and could be closed again with acetic anhydride in pyridine. An oxazolidinone derivation of benzyl 2-amino-4,6-o-benzylidene-2-deoxyβ-D-allopyranoside was prepared in a quantitative yield by a modification of a known method.

Protective group properties of the oxazolidinone were studied prior to the …
