  • Patent number: 5563264
    Abstract: A process for preparing a .beta.-lactam compound of the formula (I): ##STR1## which comprises cyclization, in the presence of a catalyst, of an azetidinone derivative of the formula: ##STR2## is provided in which R.sup.1 is hydrogen, alkyl which is optionally substituted, or amino which is optionally substituted; R.sup.2 is a carboxy-protecting group; and X is alkylene which is optionally intervened by --O-- or --S--, and/or which is optionally substituted; and R.sup.3 is aryl which is optionally substituted. The catalyst is preferably a transition metal salt (especially rhodium) or is an acid.

  • Patent number: 5561227
    Abstract: This invention provides an improved process for producing azetidinones. More particularly, this invention provides the steps of producing an azetidinone represented by the formula I ##STR1## from a carboxylic acid R.sup.2 --D--CH.sub.2 COOH, an aldehyde R.sup.1 --A--CHO and an amine RNH.sub.2, by the steps of: (a) converting a carboxylic acid to the corresponding acid chloride; (b) deprotonating a chiral oxazolidinone and treating the resulting anion with the product of step (a); (c) enolizing the product of step (b) and condensing with an imine; and (d) cyclizing the product of step (c). Steps (c) and (d) of this process are as shown in the following reaction scheme.

  • Patent number: 5521307
    Abstract: A chiral process for preparing compounds of the formula: ##STR1## from a compound of the formula: ##STR2## in which the compound formula (IV) is reacted with trimethylsilyl iodide to remove the chiral auxiliary at the 7-position and the carboxy protecting group. The process allows for the retention of the amino and carboxy protecting groups throughout the preparation of Compound IV. Also disclosed are novel intermediates.
