A highly diastereoselective synthesis of a 1-β-methylcarbapenem intermediate using titanium enolate of 2′-hydroxypropiophenone
摘要:
A key 1-beta-methylcarbapenem intermediate is synthesized from a highly diastereoselective condensation between the titanium enolate of 2'-hydroxypropiophenone with 4-acetoxy-beta-lactam followed by ozonolysis of the resulting ketone to the carboxylic acid.
