piperityl chlorides6 to isoprene yields adduct7, which undergoes a cis-stereoselective cyclisation to give the diastereoisomeric muurolene monohydrochlorides8. Treatment with potassium tert-butoxide affords β- and γ2- muurolene 2.
路易斯酸催化将哌啶基氯6加到异戊二烯中生成加合物7,该加合物经历顺-立体选择性环化,得到非对映异构的茂茂单盐酸盐8。与治疗钾,叔丁醇钾,得到β-和γ 2 - muurolene 2。
