| A NEW FACILE METHOD FOR THE SYNTHESIS OF AZACROWN ETHERS BY USING BENZYLSULFONAMIDE AS A SOURCE OF NITROGEN | |
| 摘 要： | Benzylsulfonamide was used as a source of nitrogen in the syn-thesis of azacrown ethers,and the cyclic intermediates were easily deben-zylsulfonylated by treating with CaF_2/H_2SO_4 to afford the azacrown ethers. |
