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.
