title: Convergent syntheses of oral THF 1beta-methylcarbapenems.
abstract: Convergent syntheses of oral THF 1beta-methylcarbapenems 4 (OCA-983) and 5 starting from M2-phosphate 1 were developed. Reaction of the M2-phosphate 1 with THF thiols containing a requisite prodrug side chain, 9 and 10, gave the desired oral THF 1beta-methylcarbapenems 4 and 5, respectively, in 46% and 42% overall yields.
