[摘要]：An efficient route for the prepn. of 1,3-dihydroisobenzofurans based on the iodine-mediated cyclization of 2-vinylbenzyl alcs., which can be prepd. feasibly by reactions of 2-vinylphenyllithiums with carbonyl compds., is reported. Substitution reactions of the iodo moiety of the resulting 1-(iodomethyl)-1,3-dihydroisobenzofurans with tributyltin hydride and sodium thiolates are also described.
