established methodology for the direct synthesis of glycidic amides from tertiary allyl amines, the synthesis of the enantiomers of tedanalactam were completed in two steps from the corresponding chiral dihydropiperidine. Additionally, the (+)- and (−)-enantiomers of piplaroxide were obtained from their respective tedanalactam precursor, and the absolute configuration of the naturally occurring (+)-piplaroxide
突显了最近建立的从叔烯丙基胺直接合成缩水甘油酰胺的方法,从相应的手性二氢哌啶中分两步完成了他那拉坦对映体的合成。另外,从它们各自的他达那他坦前体中获得了吡哌醇氧化物的(+)-和(-)-对映异构体,并确定了天然存在的(+)-吡哌醇氧化物的绝对构型。本方法不仅代表了最短的(-)-tedanalactam合成,而且代表了第一个总的(+)-piplaroxide合成,这是一种对切叶蚁Atta cephalotes的驱避剂。
