Resumo
Ethyl 2-methyl-4-(diethoxyphosphoryl)-4,7-dihydro-5 Н -thiopyrano[3,4- b ]furan-5-carboxylate was synthesized. It was shown that at elevated temperatures it is acetylated in presence of tin tetrachloride and chloromethylated with paraformaldehyde-hydrogen chloride system in the presence of zinc dichloride at the positon 3 of heterocyclic system. Reaction of chloromethyl derivative with N -, S - and О -nucleophiles were studied.
