摘要：
Lewis acid mediated cyclization of 2,3-epoxypropylbenzoylcarbamates is described. trans-Aryl-substituted epoxy carbamates cyclized to 4-(alpha-benzoylbenzyl)-1,3-dioxolan-2-ones and 4-aryl-3-benzoyl-5-hydroxymethyloxazolidin-2-ones. On the contrary, cis-aryl- and alkyl-substituted epoxy carbamates gave only 4-[1-(benz-oyloxy)alkyl]oxazolidin-2-ones. Mechanism of this cyclization is also discussed.
