Tosylates and mesylates were directly converted into the corresponding nitroalkanes, by their treatment with tetrabutylammonium nitrite (TBAN) under mild conditions.
对苯磺酸基和甲磺酸基直接通过与四丁基铵亚硝酸盐(TBAN)在温和条件下处理,转化为相应的硝基烷。
1-Nitroicosane as the Key Building Block for the First Synthesis of Triacontan-11-ol, A New Fatty Alcohol Isolated from<b>
<i>Argemone mexicana</i>
</b>
<b />
The first synthesis of triacontan-11-ol, a new fatty alcohol isolated from Argemone mexicana, has been realized starting from the nitroaldol reaction of 1-nitroicosane with decanal. Dehydration of the obtained nitroalkanol gives a long-chain nitroalkene which is then reduced to the corresponding nitroalkane. Nef transformation of the latter produces a ketone that is easily reduced to the fatty alcohol 9 in 21% overall yield.
