| titleOfInvention | Process for preparing an enol silyl ether compound |
| abstract | A process for preparing an enol silyl ether compound from a diazoacetoacetic acid ester having the general formula (IV): ##STR1## wherein R 1 is a lower alkyl group having 1 to 6 carbon atoms, phenyl group, a substituted phenyl group, an aralkyl group or allyl group, and R 2 , R 3 and R 4 are the same or mutually different and each is a lower alkyl group having 1 to 6 carbon atoms, which comprises reacting a diazoacetoacetic acid ester having the general formula (I): ##STR2## wherein R 1 is the same as defined above, with a trialkylsilyl chloride having the general formula (II): ##STR3## wherein R 2 , R 3 and R 4 are the same as defined above, in an inert solvent in the presence of an organic base and an alkali halide having the general formula (III): n n MX (III) n n wherein M is an alkaline metal and X is bromine atom or iodine atom. The desired compound is useful as an intermediate for synthesis of carbapenem β-lactam antibiotics. |
