Abstract
PURPOSE: To reaction between 7-aminocephalosporanic acid derivative and a novel active thioester affords a cephalosporanic acid derivative used as an antibiotic with a very wide range of antibiotic spectrum with high safety in high yield.
CONSTITUTION: The reaction of 7-aminocephalosporanic acid derivative of formula I(R1 is halogen, azide, acetoxy) or its salt with with a 1-methyl-tetrazol-5-ylthiol ester of formula II (R2 is trifuoromethylthioacetic acid) gives the objective compound of formula III. A new compound of thioester of formula II has a almost the same level of reactivity as an acid chloride or mixed acid anyhdride, which are said to be highest reactive in acylations and effects acylations not only in the 7-position but also in the 3-position. The compound of formula II is obtained from a compound of formula IV and 2-trifluoromethylacetic acid in high yield.
