overall yield of 23% has been found by the selective transformations of deca-1,4,9-trien-1-yltrimethylsilane. Thus, under mild conditions, by the hydrogenation of (I) with the aid of 9-borabicyclo[3.3.1]nonane (9-BBN) followed by oxidation with H2O2 (E,E)-deca-6,8-dienol was obtained with a yield of 60%, and this was converted quantitatively into the corresponding tosylate. The ethynylation of the latter
通过选择性转化,发现了从 deca-1,4,9-triene (I) 到 (E,E)-dodeca-8,10-dienol (II) 的五个阶段的过渡,总产率为 23% deca-1,4,9-trien-1-yltrimethyl硅烷。因此,在温和的条件下,通过 (I) 在 9-硼双环 [3.3.1] 壬烷 (9-BBN) 的帮助下氢化,然后用 H2O2 (E,E)-deca-6,8-二烯醇氧化得到以 60% 的产率获得,并将其定量转化为相应的甲苯磺酸盐。后者与乙炔化锂的乙炔化在 Lindlar 催化剂上得到 (E,E)-dodecadien-1-yne (III),然后所得三烯与 9-BBN 反应,如上文 (I) 所述,得到所需的密码素 (II)。讨论了所得化合物的IR、PMR、13C NMR、UV和质谱。
