  Asymmetric Synthesis of 2-Alkyl-Perhydroazepines from [5,3,0]-Bicyclic Lactams

  摘要：

  The synthesis and utility of a novel class of [5,3,0]-bicyclic lactams are described. Produced by the cyclodehydration of (R)-phenylglycinol with omega -keto acids, lactams 4-6 were obtained as separable diastereomeric mixtures (similar to2:1) in low yields (similar to 40%). Higher chemical yield (up to 61%) was realized tia an alternate route involving ring closure metathesis of 2-allyl-N-acroyl oxazolidines, 8. Stereoselective reductions of the syn-bicyclic lactams, 4a and 5a, occurred with the use of alane or lithiumaluminum hydride, affording azepine alcohols, 11a and;15a, of the R configuration at the 2-position, in good to moderate yields (50-88%). High selectivity was also observed in the diisobutylaluminum hydride reduction of the epimeric anti lactams, 4b and 5b, affording azepine alcohols, 11b and 15b, of the S configuration at C-2. Hydrogenolytic cleavage of the N-benzyl moiety afforded chiral 2-substituted perhydroazepines, (R)- and (S)-12, in good yields and good enantiomeric excesses (84-94%).

  A novel selective fragmentation of cycloalkanones by NaNO2/HCl has been established. The C–C bond cleavage reaction proceeds smoothly under mild conditions, selectively affording versatile keto acids or oxime acids. The methodology can streamline the synthesis of valuable chiral molecules and isocoumarins from readily available feedstocks.

  日期：——

  A new method for the direct conversion of carboxylic acids to aldehydes using N,N-dimethylchloromethyleniminium chloride and lithium tri-t-butoxyaluminum hydride was established. This method provides a convenient way for the chemoselective reduction of carboxylic acids even with such a functional group as halide, ester, nitrile, olefin, and ketone.

• One-pot room-temperature conversion of cyclohexane to adipic acid by ozone and UV light
  作者：Kuo Chu Hwang、Arunachalam Sagadevan

  DOI：10.1126/science.1259684

  日期：2014.12.19

  Nitric acid oxidation of cyclohexane accounts for ~95% of the worldwide adipic acid production and is also responsible for ~5 to 8% of the annual worldwide anthropogenic emission of the ozone-depleting greenhouse gas nitrous oxide (N ₂ O). Here we report a N ₂ O-free process for adipic acid synthesis. Treatment of neat cyclohexane, cyclohexanol, or cyclohexanone with ozone at room temperature and 1 atmosphere of pressure affords adipic acid as a solid precipitate. Addition of acidic water or exposure to ultraviolet (UV) light irradiation (or a combination of both) dramatically enhances the oxidative conversion of cyclohexane to adipic acid.

  环己烷的硝酸氧化占全球己二酸产量的约95％，也占全球年人为排放的臭氧层破坏温室气体一氧化二氮（N2O）的5％至8％。我们报道了一种无 的己二酸合成工艺。在室温和1大气压下，对纯环己烷、环己醇或环己酮进行臭氧处理，生成己二酸作为固体沉淀。加入酸性水或暴露于紫外（UV）光照射（或两者结合）显著增强了环己烷氧化转化为己二酸。
