6-alkyl-3,4-dihydro-2H-pyrans is highly stereoselective and gives tri-substituted alkenes with retention of configuration. The method was applied to the synthesis of (E)-3-Acetoxy-7-methyl-6-nonene, the aggregation phermone of the square-necked grain beetle.
某些Grignard试剂与6-烷基-3,4-二氢-2H-吡喃的镍催化偶联具有很高的立体选择性,并可以保留构型的三取代烯烃。该方法应用于方颈甲虫的聚集信息素(E)-3-乙酰氧基-7-甲基-6-壬烯的合成。
