Title:
NOVEL METHOD FOR SYNTHESIS OF INTERMEDIATE IN SYNTHESIS OF CARBAPENEM USING SUGAR TEMPLATE
Document Type and Number:
WIPO Patent Application WO/2007/013592
Kind Code:
A1
Abstract:
Disclosed is a method for producing an intermediate in the synthesis of a useful carbapenem anti-bacterial agent with good efficiency, more specifically the method described above which enables the introduction of a methyl group into position 1 of the carbapenem skeleton in a highly stereoselective manner and does not need the use of any expensive asymmetric auxiliary group, any catalyst that may cause an ultra-low temperature reaction or have any toxicity to a human body or the like and can recover the auxiliary group. In this method, a sugar template containing a propionate unit represented by the formula (II) is reacted with an acetoxyazetidinone represented by the formula (III) to form a carbon-carbon bond between them, thereby introducing a methyl group into position 1 of the carbapenem skeleton in the desired β-stereoselective manner.
