Rhodococcus erythropolis SET1, a novel nitrilehydrolysing bacterial isolate, has been undertaken with 34 nitriles, 33 chiral and 1 prochiral. These substrates consist primarily of β-hydroxy nitriles with varying alkyl and aryl groups at the β position and containing in several compounds different substituents α to the nitrile. In the case of β-hydroxy nitriles without substitution at the α position

Mutations in oncogenes and tumor suppressors contribute to the development and progression of cancer. The present disclosure describes compounds and methods that restore DNA binding affinity of p53 mutants. The compounds of the present disclosure can bind to mutant p53 and restore the ability of the p53 mutant to bind DNA and activate downstream effectors involved in tumor suppression. The disclosed compounds can be used to reduce the progression of cancers that contain a p53 mutation.
A highly regio- and stereoselective Pd-catalyzed tandem allylic rearrangement/intramolecular decarboxylative coupling of aryl propiolates derived from Baylis–Hillman adducts
A highly regio- and stereoselective Pd-catalyzed tandem allylic rearrangement/intramolecular decarboxylative coupling of aryl propiolates derived from Baylis–Hillman alcohols leading to the formation of an important class of 1,5-diarylpent-1-en-4-ynes has been developed. The aryl propiolates of Baylis–Hillman alcohols derived from methyl acrylate provided exclusively (E)-1,5-diarylpent-1-en-4-ynes

mixed at different proportions can give good to excellent yields and short reaction times for the Morita–Baylis–Hillman reaction. The present Letter details our findings in the Morita–Baylis–Hillman reaction between several aromatic aldehydes and methyl acrylate or acrylonitrile. The selection of the catalyst was also evaluated and DABCO affored the best results when compared to DBU, DMAP, HMT, Imidazole
Regioand stereoselective synthesis of N -substituted azole acrylonitriles has been achieved smoothly in N,N -dimethylformamide (DMF) in the presence of potassiumcarbonate (K2 CO3) as a base catalyst. N -Substituted azole acrylonitriles were obtained in moderate to good yields (39%–87%) with a one-pot reaction between readily available N -acetylazoles and Baylis-Hillman nitriles. The structural determinations
在碳酸钾(K2CO3)作为碱催化剂存在下,在N,N-二甲基甲酰胺(DMF)中顺利实现了N-取代的唑丙烯腈的区域和立体选择性合成。在容易获得的N-乙酰基唑与Baylis-Hillman腈之间进行一锅法反应后,以中等至良好的收率(39%–87%)获得了N-取代的唑丙烯腈。结构测定通过NOESY 1 H NMR和X射线晶体学完成。
