  α,β-Dehydrogenation of esters with free O H and N H functionalities via allyl-palladium catalysis

  摘要：

  A direct and selective method for the alpha,beta-dehydrogenation of esters using palladium catalysis in the presence of free O-H and N-H functionalities is reported herein. Allyl-palladium catalysis allows for preservation of readily oxidizable functionalities such as amines and alcohols. Furthermore, an economical protocol using LDA was developed for the dehydrogenation of beta-amino esters. (C) 2018 Elsevier Ltd. All rights reserved.

• Second-GenerationcycloSal-d4TMP Pronucleotides Bearing Esterase-Cleavable Sites — The “Trapping” Concept

  An extension of the cycloSal-pronucleotide approach is presented. Attachment of an enzyme-cleavable ester/acylal group to the cycloSal-d4TMP triesters should allow these compounds to be trapped intracellularly after cleavage. The ester/acylal groups were introduced in the 3- or 5-position of the cycloSal ring system, and surprising differences were observed in hydrolysis studies in CEM cell extracts

  介绍了 cycloSal-核苷酸方法的扩展。将酶可裂解的酯/酰基基团连接到 cycloSal-d4TMP 三酯上应该允许这些化合物在裂解后被捕获在细胞内。在环Sal环系统的3-或5-位引入酯/酰基基团，并且在CEM细胞提取物的水解研究中观察到关于酯/酰基部分的惊人差异。虽然乙酰基酯和乙酰丙酸酯很容易裂解，但 cycloSal-d4TMP 酸的烷基酯证明对酶促裂解具有抗性。相比之下，AM-、POM- 和 POC-酰基在提取物中迅速裂解，产生 cycloSal-d4TMP 酸。还介绍了化合物对 HIV 的抗病毒活性。(© Wiley-VCH Verlag GmbH & Co.

  extent, chlorides and triflates to α,β-unsaturated carbonyls at room temperature, without requiring the previous formation of an organometallic nucleophile. The reaction proceeds inter- and intramolecularly with good functional group compatibility, which is key for the development of free protecting group methodologies. Carbo- and heterocycles of five- and six-membered rings are obtained in good yields.
