摘要：

4,5-Dimethylene-1,2-dioxane (1) was prepared by zinc-induced debromination of 4.5-bis (bromomethyl)-1,2-dioxacylohexa-4-en (4) obtained from 2,3-bis (bromomethly-1,3-butadiene (3) by reaction with singlet oxygen. Diels-Alder additions of 1 with singlet oxygen, dimethyl acetylenedicarboxylate and N-methyl-1,2,4-triazoline-3,5-dione gave adducts 2,6 and 8 respectively. 3,4-Disubtituted furans 5 and 9 were obtained from peroxides 4 and 8 by cobalt (II) tetraphenylporphyrin catalyzed rearrangement.
