合成路线1
该中间体在本合成路线中的序号：(VIII)(R)-4-hydroxy-2-pyrrolidinone (I) was protected as the tert-butyldimethylsilyl ether, and then converted to tert-butyl carbamate (II) by means of Boc2O. Subsequent condensation of (II) with Grignard reagent (III), followed by reduction with NaBH4, and acetal hydrolysis yielded the pyrrolidinyl benzaldehyde (IV). Horner-Emmons reaction of (IV) with phosphonate (V) produced the cinnamic acid derivative (VI), and further Michael addition to (VI) of the chiral lithium amide (VII) furnished aminoester (VIII). After hydrogenolysis of both N-benzyl groups of (VIII), the resulting primary amine (IX) was protected with Boc2O, and the silyl ether was then cleaved by means of tetrabutylammonium fluoride to give the hydroxypyrrolidine derivative (X). This was converted to the required thiol (XI), which was then coupled with the carbapenem phosphate (XII). Finally, hydrogenolysis of the 4-nitrobenzyl ester of (XII) provided the title compound.
