An efficient synthesis of the title compound 14 is reported, which employs the ZnCl2/Et2O catalyzed addition of acetyl chloride (4) to 2-methyl-2-butene (5) and the [3+ + 2] cycloaddition of the 1,1,2,3-tetramethylallyl cation to 2,3-dimethyl-2-butene as key steps.
报告了标题化合物14的有效合成,该化合物使用ZnCl 2 / Et 2 O催化的乙酰氯(4)加到2-甲基-2-丁烯(5)上,并[3 + + 2]环加成。 1,1,2,3-四甲基烯丙基阳离子生成2,3-二甲基-2-丁烯为关键步骤。
