  Synthesis and structure–activity studies of the V-ATPase inhibitor saliphenylhalamide (SaliPhe) and simplified analogs

  摘要：

  An efficient total synthesis of the potent V-ATPase inhibitor saliphenylhalamide (SaliPhe), a synthetic variant of the natural product salicylihalamide A (SaliA), has been accomplished aimed at facilitating the development of SaliPhe as an anticancer and antiviral agent. This new approach enabled facile access to derivatives for structure-activity relationship studies, leading to simplified analogs that maintain SaliPhe's biological properties. These studies will provide a solid foundation for the continued evaluation of SaliPhe and analogs as potential anticancer and antiviral agents. (C) 2015 Elsevier Ltd. All rights reserved.

  2-diamine with methyl 2-formylbenzoate catalyzed by a chiral phosphoric acid represents the first efficient method for the preparation of medicinally interesting chiral 2,3-dihydro-1H-imidazo[2,1-a]isoindol-5(9bH)-ones with high yields and excellent enantioselectivities. This strategy has been shown to be quite general toward various methyl 2-formylbenzoates.

  Abstract DBU-CH3I has been poised to be a substitute for diazomethane in the preparation of methyl esters from carboxylic acids. The reactions can be carried out in commercial untreated acetone and acetonitrile, which have been exemplified with several methyl esters, otherwise it is difficult to prepare. Bis-esterification using diiodomethane can also be achieved in a similar fashion. Sufficiently

  摘要 DBU-CH3I 已准备好在由羧酸制备甲酯中替代重氮甲烷。反应可以在商业未处理的丙酮和乙腈中进行，已经以几种甲酯为例，否则很难制备。使用二碘甲烷的双酯化也可以类似方式实现。足够酸性的酚也可以方便地通过该方法O-甲基化。

  have been accomplished via tandem Mannich-lactamization and aldol-lactonization reactions, respectively. A variety of enantioenriched isoindolinones (up to 99% ee) and phthalides (up to 85% ee) containing α-diazoesters were afforded in excellent yields. Furthermore, a concise synthesis of (S)-PD 172938 has been demonstrated by using this protocol.

  The stereoselective total synthesis of (−)-varitriol has been achieved starting from commercially available d-(−)-ribose and o-anisic acid. A Mitsunobu reaction, Julia–Kocienski olefination, and one pot reduction of both ester and iodo functionalities with superhydride are the key reactions involved in this synthesis.

  从商业上可获得的d-（-）-核糖和邻-茴香酸开始已经实现了（-）-varitriol的立体选择性全合成。Mitsunobu反应，Julia-Kocienski烯烃化反应以及用超氢化物一锅同时还原酯和碘官能团是该合成过程中的关键反应。

  strong ortho-directing group. In the initial route, tertiary amide cleavage during final step was challenging, but cleaving the tertiary amide before Wittig reaction was beneficial. The Wittig reaction with protected carboxylic group (methyl ester) resulted in side-products whereas using sodium salt resulted in higher yields. The novel compounds were screened for antibacterial activity and cytotoxicity

  熊果酸衍生物表现出广泛的生物学活性。在本报告中，探索了一种合成脱水萘酸衍生物的有效方法，并合成了一小套水杨酸变体，这些变体保留了恒定的疏水性元素（萘基尾巴）。经由Wittig反应引入萘基侧链，并使用取代的邻茴香酸的直接邻位金属化反应安装醛。失败邻-metalation使用未保护的羧酸基团迫使我们使用定向邻位-metalation其中叔酰胺用作强邻指导小组。在最初的途径中，在最终步骤中裂解叔酰胺是具有挑战性的，但在Wittig反应之前裂解叔酰胺是有益的。带有受保护的羧基（甲酯）的Wittig反应产生副产物，而使用钠盐则产生更高的收率。筛选了新型化合物的抗菌活性和细胞毒性。尽管在水杨酸根基团上的取代增强了抗菌活性，但它们也增强了细胞毒性。
