cyclohexane, and 40 ml of MeOH is passed (at 5°C) 0.2 M O3/O2, the solution is decanted off, and the precipitated ozonide is dissolved in 200 ml of MeOH and is reduced with 19 g of NaBH4 (40°C) with the isolation, after the usual working up, of 23.4 g of octane-1,8-diol (II). From 0.5 mole of (II) and 0.6 mole of 45% HBr 8-bromooctan-1-ol (III) is obtained and this is converted into 1-(2-THPL)oxy)-8-bromooctane
提出了一种基于环辛烯 (I) 的十六进制-9Z-烯醛的合成——棉铃虫 Heliothis armigera (Hübner) 的性信息素的组成部分。将 0.2 M O3/O2 通入 22 g (I)、250 ml 环己烷和 40 ml MeOH 的溶液中(在 5°C 下),倾析出溶液,将沉淀的臭氧化物溶于 200 ml MeOH 并用 19 g NaBH4 (40°C) 还原,在常规处理后分离出 23.4 g 辛烷-1,8-二醇 (II)。由0.5摩尔(II)和0.6摩尔45%HBr得到8-溴辛烷-1-醇(III)并将其转化为1-(2-THPL)氧基)-8-溴辛烷(IV)。(IV) 与 oct-1-yne(Ar、LiNH2、HMPTA,10°C,1 小时,然后 55°C,10 小时)缩合生成 1-(2-THPL-oxy)hexadec-9- yne (V) 水解 (MeOH, H2O, p-TsOH
