摘要:
A novel process for preparing enantiomerically-pure 3-methyl-5-(1-(C1-C3-alkyl)-2-pyrrolidinyl)isoxazole in high yield, wherein a protected pyrrolidine or 2-oxo-pyrrolidine starting material is reacted with a suitable organic anion and a resulting beta-keto oxime intermediate is cyclized and dehydrated, as well as intermediates useful in the preparation thereof.
