  3- and 4-Dialkoxyphosphorylmethyl Derivatives of 5-tert-Butylfuran with Electron-Withdrawing Substituents in Position 2

  摘要：

  A procedure for preparing 3- and 4-halomethyl derivatives of 5-tert-butylfuran containing electron-withdrawing substituents in position 2 was developed, and phosphorylation of the resulting products under the conditions of the Arbuzov and Michaelis-Becker reactions was studied. 3-Bromomethyl derivatives are phosphorylated with trimethyl phosphite considerably faster than their 4-chloromethyl analogs. At the same time, 3- and 4- chloromethyl derivatives of N,N-diethyl-5-tert-butylfuran-2-carboxamide under the conditions of the Michaelis-Becker reaction only slightly differ in chemical properties.

  Synthesis and Phosphorylation of 2-, 3-, and 4-Halomethyl-5-tert-butylfurans

  摘要：

  Synthetic methods for preparing of 2-, 3-, and 4-halomethyl-5-tert-butylfurans are developed. It was established that the bromination of 3- and 4-methyl-2-tert-butylfurans with N-bromosuccinimide proceeds mainly at the free alpha-position of the furan ring, and not at the methyl group. Therefore, the target halomethylfurans were prepared through the corresponding 3- and 4-methoxymethyl derivatives. The obtained five products were phosphorylated with sodium diethyl phosphite under the conditions of the Michaelis-Becker reaction to give the corresponding phosphonates.
