On a sulfurated grignard reagent equivalent to that of 2-chloromethyl-1,3-butadiene. New syntheses of ipsenol (2-methyl-6-methylene-7-octen-4-OL) and of (E)-β-farnesene ((E)-7,11-dimethyl-3-methylene-1,6,10-dodecatriene)

Experiments on the synthesis of (3-methylene-4-chloro)butylphenyl sulfide, which is the precursor of the corresponding Grignard reagent, are described. With two typical electrophiles, namely isovaleraldehyde and geranyl chloride, this reagent provides the title terpenes in two further simple steps (oxidation to sulfoxides and thermolysis).
描述了作为相应格氏试剂的前体的(3-亚甲基-4-氯)丁基苯硫醚的合成实验。使用两种典型的亲电试剂,即异戊醛和香叶基氯,该试剂可在另外两个简单的步骤(氧化为亚砜和热分解)中提供标题萜烯。
