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.
