Amides derived from pyrrolidine and methyl (S)-lactate, methyl (S)-2-hydroxy-3-phenylpropanoate, or methyl (S)-2-hydroxy-3-methylbutanoate, after O-benzylation and O-silylation have been treated with EtLi or EtMgC1 under suitable conditions, to give excellent overall yields of enantiopure ethyl keto
Dibromoketene is prepared by in-situ Zn dehalogenation of tribromoacetyl bromide in the presence of POC1,. Under these conditions, the cycloaddition of dibromoketene with olefins 5 yields a,&-dibromocyclobutanones 2, which are cleaved with alkoxides to yield@-dibromomethyl esters 4. Several examples
