Ring opening oxazoline

In another example, treatment of an oxazoline ester with TMSCl in THF at reflux leads to oxazoline ring opening and furnishes the corresponding 8-chloro-ainino ester in quantitative yield (eq 52). Treatment with TMSBr and TMSI at rt affords the corresponding /3-halo-amino esters in quantitative yield. [Pg.113]

The substrate monomer was synthesized via conventional chemical methods [96]. During enzymatic reaction, three kinds of reactions are possible polymerization of the monomer to synthetic HA, enzymatic and nonen-zymatic hydrolysis of the monomer via the oxazoline ring opening, leading to the GlcA (l 3)GlcNAc disaccharide (Scheme 26). [Pg.197]

Elaboration of (19) involved conversion to an oxazoline, ring-opening and chlorination at the 4-position followed by reduction to eventually give the benzyl ester of 3-ANA benzyl ether. Subsequent acylation and deprotection led to nocardicin A. [Pg.7]
