Ï-Nitro ketoaliphatic compounds 3a and 3b, prepared by a new and efficient route, have been elaborated to short syntheses of both 2,7-dimethyl-1,6-dioxaspiro[4.6]undecane, [(2S,5R,7S)-1a] and 2,7-diethyl-1,6-dioxaspiro[4.6]undecane [(2S,5R,7S)-1b], the pheromones produced by Andrena haemorrhoa and Andrena wilkella, respectively.
通过新的高效路线制备的Ï-硝基酮脂族化合物 3a 和 3b,已被详细阐述为 2,7-二甲基-1,6-二氧杂螺[4.6]十一烷 [(2S,5R,7S)-1a] 和 2,7-二乙基-1,6-二氧杂螺[4.6]十一烷 [(2S,5R,7S)-1a] 的简短合成。6]十一烷[(2S,5R,7S)-1a]和 2,7-二乙基-1,6-二氧杂螺[4.6]十一烷[(2S,5R,7S)-1b]的简短合成,它们分别是 Andrena haemorrhoa 和 Andrena wilkella 产生的信息素。
