A new, simple, cheap, and practical procedure for the direct transformation of α,β-unsaturated nitroalkenes into ketones has been realized by the NaBH4/H2O2 system. By this method, other functional groups such as C-C double bonds, ketals or aromatic nitro groups were preserved. Application of this methodology to the preparation of 4-oxoalkanoic acids, dihydrojasmone, and (±)-exo-brevicomin is also reported.
通过 NaBH4/H2O2 系统实现了一种新的、简单、廉价和实用的δ,δ-不饱和硝基烯烃直接转化为酮的过程。通过这种方法,C-C 双键、酮或芳香族硝基等其他官能团得以保留。此外,还报道了应用这种方法制备 4-氧代烷酸、二氢茉莉酮和 (±)-exo-brevicomin 的情况。
