| 英文摘要 | Bis (tributyltin)-initated atom transfer cyclization reactions of 3-butenyl iodoalkanoates in the presence of BF^3.Oet^2 as the catalyst afforded the 6-exo cyclization products as a mixture of 3,4-cis-and trans-substituted tetrahydro-2H-pyran-2-ones in 53--71% yield with the major isomers being the cis ones. Ab initio calculations at the B3LYP/6-31G* level on the transition states of the radical cyclization and on the cyclized products revealed that the reactions are kinetically controlled and the transition states for the 6-exo radical cyclization are in boat conformations. Moreover, the cisoriented transition states are of lower energy than the corresponding trans-oriented ones, which are in excellent agreement with experimental results. |
