Starting from commercially available ketones, a reproducible and reliable strategy for the synthesis of tetrasubstituted nitroalkenes was successfully developed, using a two-step procedure; the HWE olefination of the ketone to form the corresponding α,β-unsaturated esters is followed by a nitration reaction to introduce the nitro group in the α position of the ester group. The enantioselective organocatalytic
从市售酮类开始,成功开发了一种可重现且可靠的四取代硝基烯烃合成策略,采用两步法;酮的 HWE 烯化形成相应的 α,β-不饱和酯,然后进行硝化反应,在酯基的 α 位引入硝基。还初步研究了这些化合物的对映选择性有机催化还原,以获得功能化的对映体富集的硝基烷烃,这是进一步合成的有用原料。还原产物的绝对构型是通过手性硝基烷烃与已知产物的化学关联确定的;
