This paper reports the synthesis and insecticidal activity of a series of novel 4-hydroxy-3-mesityl-1-methoxymethoxy-1,5-dihydro-2H-pyrrol-2-one derivatives, in which the substituents at the 5-position were varied with a number of alkyl and spirocycloalky

The higher N-benzylidene-α-amino acid methyl ester N-oxides 3c-t were obtained from the lower nitrone esters 3a and b by base induced alkylation in α-position of the N->O-group.The compounds 3 were converted into the N-hydroxy-α-amino acid methyl esters 6 by heating with hydroxylamine hydrochloride in ethanol and into N-hydroxy-α-amino acids 7 with concd. hydrochloric acid. - Compound 3d was, on heating in toluene, converted to methyl 1-aza-7-oxabicycloheptanecarboxylate 8 by intramolecular cycloaddition.
