    摘要: 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-serylaminomalonate is cyclized with 200 mole % TPP-diisopropylazodicarboxylate to N-(diethoxycarbonylmethyl)-3-protected-amino-2-azetidinone. The 2-azetidinones provided are useful intermediates.

    摘要: Monocyclic .beta.-lactam compounds represented by the formula ##STR1## wherein R.sub.1 is H, NH.sub.2, acylamino, C.sub.1 -C.sub.4 alkyl, etc.; R.sub.2 is e.g. C.sub.1 -C.sub.4 alkyl, hydroxyalkyl, aminoalkyl, carboxy, esterified carboxy, esterified carboxyalkyl, or carboxyalkyl; and R.sub.3 is hydrogen, benzyl, substituted benzyl, pivaloyl, --SO.sub.3 M, or --P(C.dbd.O)(OM')2; are obtained by the cyclization of an O-substituted hydroxamate of a .beta.-substituted alkylcarboxylic acid. For example, .alpha.-ethylmalic acid monobenzyl ester is reacted with O-benzylhydroxylamine to form the O-benzylhydroxamate of the free carboxy group, and the hydroxamate is cyclized with diethyl diazodicarboxylate and triphenylphosphine to form the .beta.-lactam of the above formula wherein R.sub.1 is ethyl, R.sub.2 is benzyloxycarbonyl and R.sub.3 is benzyl. The .beta.-lactam compounds are useful intermediates for preparing .beta.-lactamase inhibitors and monocyclic .beta.-lactam antibiotics and, when R.sub.3 is --SO.sub.3 M or --P(C.dbd.O)(OM')2 the compounds and salts thereof are antibacterial agents.

    摘要: A stereoselective process for chiral intermediates to 1-carbapenum and 1-carbacephalosporins is provided comprising the use of an N-acyl-(4R)-substituted-1,3-thiazolidine-2-thione as a chiral auxiliary in boron enolate mediated aldol condensation with a protected-.beta.-keto ester aldehyde. E.g., benzyl 3,3-(ethylenedioxy)-4-formylbutyrate is condensed with the boron enolate formed with n-butyryl (4R)-methoxycarbonyl-1,3-thiazolidine-2-thione to provide benzyl 3,3-ethylenedioxy-(5R)-hydroxy-6-[(4R)-methoxycarbonyl-1,3-thiazolidine-2-thione-3-ylcarbonyl]octanoate. Displacement of the thiazolidine-2-thione chiral auxiliary moiety with an O-alkyl, O-acyl or O-aralkyl hydroxyamine provides the corresponding chiral intermediate as the hydroxamate.

    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.
