Title:
PROCESS FOR PRODUCING CARBAPENEM DERIVATIVE
Document Type and Number:
WIPO Patent Application WO/2003/089432
Kind Code:
A1
Abstract:
A process for easily producing the carbapenem derivative shown below. The process, which is for producing a carbapenem derivative represented by the following formula (5): (5) (wherein R4a means R4 or an organic group), is characterized by reacting a compound represented by the formula (1) (wherein R1 means a hydroxy-protecting group; R2 and R3 each means hydrogen or lower alkyl; R4 and R5 each means an ester residue; and Y means oxygen or sulfur) in the presence of a Lewis acid and a Lewis base and optionally causing a mercaptan derivative to act on the resultant reaction product.
