- Patent Number:
- US 4595532 B2
- Description:
N-Mono or N-disubstituted methyl-2-azetidinones are provided via cyclization of .beta.-hydroxy or .beta.-halo substituted acid sec-amides wherein the amide nitrogen is substituted with a mono- or di-substituted methyl group having activating substituents. Cyclization of .beta.-hydroxy acid amides is mediated by triphenylphosphine-dialkylazodicarboxylate while cyclization of .beta.-halo acid amides is mediated by strong bases e.g. lithium dialkylamides. E.g. Diethyl amino-protected L-serylamin…

- Description:
Bicyclic .beta.-lactams comprising a 5- or 6-membered lactone or lactam ring are obtained in a process comprising a base induced intramolecular cyclization of a 4-substututed .beta.-lactam having a leaving group in the 1-position. An intramolecular nucleophile transfer reaction is proposed as the operative mechanism and the bicyclic .beta.-lactams are obtained in the required stereochemical form for biological activity. The compounds provided are useful intermediates for the preparation of an…

- Description:
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 intermedia…

- Description:
.beta.-Hydroxy-.alpha.-amino acids are obtained via serine hydroxymethyltransferase catalyzed condensation of aldehydes with glycine. The predominant product with most aldehydes is the L-erythro diastereomer. For example, succinic semialdehyde methylester is condensed with glycine in the process to provide L-erythro .alpha.-amino hydroxy adipic acid mono methyl ester.
