The total synthesis of ritipenems. Construction of penem thiazoline ring by incorporation of two 2C units of glycolic acid.
摘要:
Short syntheses of Ritipenem Acoxyl 1a and Ritipenem 1b are reported. The syntheses start from (R)-4-acetoxy-(S)-3-[(R)-1-(t-butyldimethylsilyloxy)ethyl]azetidin-2-one 3 and are based on the incorporation of two 2C units obtained by manipulation of glicolyc acid 4.
