摘要
The intermolecular cycloadditions of a cyclic nitrone to chiral allyl ethers take place with erythro selectivity, where the degree of selectivity achieved is dependent upon the size of the alkyl substituent attached to the allylic chiral center, and these reactions are applied to the synthesis of optically active alkaloid coniine.
