Applications

Acylation of D- and DL-WV with phenoxyacetyl chloride, followed by cleavage of the t-butyl ester,afforded the penultimate penicilloic acids. Phenoxyacetyl chloride was used in the synthesis of series of macrocyclic bis-β-lactams, 5-phenyl-6-epiphenoxymethylpenicillin benzyl ester, N-protected guanosine derivatives, useful in RNA synthesis, phenyloxyketene, for cycloaddition to imines leading to β-lactams. Treatment of iminophosphoranes with phenoxyacetyl chloride afforded respectively the trans- and cis-3-(acylamino)-p-lactams. By the oxidative addition of stannous fluoride to allyliodide, with 1, 2-O-isopropylidene-D-glyceraldehyde and phenoxyacetyl chloride results in the predominant formation of erythro homoallylester, which is in turn converted into 2-deoxy-D-ribose. The 4-disubstituted P-lactams (4a-c and 6a-b) were prepared through the reaction of N,N-diphenylhydrazones and N-methyl-N-phenylhydrazones of ketones with phenoxyacetyl chloride/Et3N in dichloromethane.

Notes

Moisture Sensitive. Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Store away from strong oxidizing agents, moisture.

Can be used to protect OH groups. The phenoxyacetate group is 50x more labile to aqueous ammonia than acetate: Tetrahedron Lett., 4273 (1968). It can also be cleaved with methanolic t-BuNH 2 : Chem. Lett., 965 (1982).
