    摘要: 5'-O-Acyl-5-fluorouridines and 5'-O-acyl-5-sluorocytidines are prepared by the direct acylation of the 5'-hydroxyl group with amino acids under Mitsunobu conditions and the amino acyl derivatives are coupled with other amino acids or peptides to provide antibacterial and antifungal derivatives of the nucleosides. For example, 5-fluorouridine is acylated at the 5'-hydroxyl group with an amino protected L-valine and the acylation product is deprotected to provide 5'-O-(L-valinyl)-5-fluorouridine having activity against Gram-positive bacteria including resistant staphylococcus. Preferred peptide derivatives comprise the tripeptides of ornithine and lysine wherein the terminal amino group is substituted by both hydroxy and acetyl. The latter peptides inhibit the growth of C. albicans.

    摘要: A process for 4-halomethylazetidin-2-ones is provided which comprises mixing in an inert solvent a positive halogen reagent in the presence of a weak base with a .beta.,.gamma.-unsaturated O-acylhydroxamate of the formula ##STR1## wherein R is protected amino, lower alkyl or phenyl substituted lower alkyl, R.sub.2 is a substituent such as lower alkyl which may be substituted by formyl, hydroxy, halogen, etc., and R.sub.1 is alkoxy, benzyloxy, etc. When R is a protected amino group, the process provides cis-4-halomethylazetidin-2-ones, while when R is alkyl or phenylalkyl, the trans isomer is obtained. The 4-halomethylazetidinones are useful intermediates for known antibiotic compounds.

    摘要: Process for N-acyloxy or sulfooxy 2-azetidinones comprising O-acylation of a .beta.-hydroxy or .beta.-halo hydroxamic acid, and cyclizing the O-acylhydroxamate with TPP-CCl.sub.4 -TEA or with TPP-dialkylazodicarboxylate to the N-acyloxy-2-azetidinone. Solvolysis of the acyl group provides an N-hydroxy-2-azetidinone. E.g., N-Cbz-L-serine is converted to the O-acetyl hydroxamate, cyclized and solvolyzed to N-hydroxy-3-(Cbz-amino)-2-azetidinone. The N-hydroxy-2-azetidinones are useful intermediates to monocyclic .beta.-lactam antibiotics and .beta.-lactamase inhibitors.
