Preparation of beta-lactam compounds, and intermediates therefor |
| abstract |
A process for preparing a β-lactam compound of the formula (I):n n which comprises cyclization of an azetidinone derivative of the formula:n n in which R¹ is hydrogen, alkyl which is optionally substituted, or amino which is optionally substituted; R² is a carboxy - protecting group; and X is alkylene which is optionally intervened by -O- or -S-, and/or which is optionally substituted; and R³ is aryl which is optionally substituted. |
