Abstract

2-(Arylmethoxy)methyl-2-oxazolines, on treatment with LDA in THF at low temperature, rearrange to afford products which are hydrolysed to ortho-methylmandelic acids or a-(l-methyl-2-naphthyl )glycolic acid. ... 2-(Alkoxy)methyl-2-oxazolines, on treatment with LDA in THF at low temperature, give the stable lithium azaenolates, which can react with electrophiles to yield a-substituted products. However, 2-(benzyloxy)methyl-2-oxazoline la, when subjected to ...
