For the assignment of the configuration at C(8) and C(15) of the natural oviposition-deterring pheromone 1 in Rhagoletis cerasi L., the four possible stereoisomers of 1 are synthesized. By condensing the C6 building blocks (5R)-4 and (5S)-4 with the boron enolates of the C10 building blocks (4S)-13 and (4R)-13, followed by decarboxylative dehydration, all stereoisomers of 16 are available (Scheme 5)
为了赋予Rhogoletis cerasi L.中的天然产卵信息素1在C(8)和C(15)的构型,合成了四种可能的立体异构体1。通过将C 6结构单元(5 R)-4和(5 S)-4与C 10结构单元(4 S)-13和(4 R)-13的硼烯醇缩合,然后进行脱羧脱水,有16种立体异构体可供选择(方案5)。脱保护后,16的糖基化,随后形成牛磺酸酰胺,得到四个立体异构体(8 R,15 S)-1,(8 R,15 R)-1,(8 R,15 S)-1和( 8 S,15 S)-1(方案6)。
