摘要:
Previously unknown (Z)-3,4,4,4-tetrachlorobut-2-enoateslb-20b were prepared in 77-88%yieldsby reaction in the presence of pyridine of 3,3,4,4,4-pentachlorobutanoic acid chloride with cetyl alcohol (1a), terpenols and terpenone oximes (2a-13a), sterols (14a and 15a), diosgenin (16a), and plant phenols and their oximes (17a-20a).
