An umpolung oxa-[2,3] sigmatropic rearrangement employing arynes for the synthesis of functionalized enol ethers

Gaykar, Rahul N.,George, Malini,Guin, Avishek,Bhattacharjee, Subrata,Biju, Akkattu T.

supporting information, p. 3447 - 3452 (2021/05/04)

An oxa-[2,3] sigmatropic rearrangement involving arynes is reported featuring the umpolung of ketones, where the C=O bond polarity is reversed. The in situ-generated sulfur ylides from β-keto thioethers and arynes undergo efficient rearrangement allowing the facile and robust synthesis of functionalized enol ethers in high yields and excellent functional group compatibility. Preliminary mechanistic studies rule out the possibility of Pummerer-type rearrangement operating in this case.

Nucleus-independent chemical shift (NICS) as a criterion for the design of new antifungal benzofuranones

González-Chávez, Marco Martín,González-Chávez, Rodolfo,Méndez, Francisco,Martínez, Roberto,Ni?o-Moreno, Perla Del Carmen,Ojeda-Fuentes, Luis Enrique,Richaud, Arlette,Zerme?o-Macías, María de los ángeles

, (2021/08/30)

The assertion made by Wu et al. that aromaticity may have considerable implications for molecular design motivated us to use nucleus-independent chemical shifts (NICS) as an aromaticity criterion to evaluate the antifungal activity of two series of indol-4-ones. A linear regression analysis of NICS and antifungal activity showed that both tested variables were significantly related (p –1 for Candida glabrata, Candida krusei and Candida guilliermondii with compounds 15-32, 15-15 and 15-1. The MIC for filamentous fungi was 1.95 μg·mL–1 for Aspergillus niger for compounds 15-1, 15-33 and 15-34. The results obtained support the use of NICS in the molecular design of compounds with antifungal activity.

A photoactivatable microRNA probe for identification of microRNA targets and light-controlled suppression of microRNA target expression

Chen, Lei,Li, Jinbo,Sun, Yu.,Zhang, Yan

supporting information, p. 627 - 630 (2020/01/29)

Here, we report a novel dual-functional microRNA (miRNA) probe, PA-miRNA, for miRNA target identification and light control of miRNA target expression. PA-miRNA is a miRNA mimic with a 3′-biotin tag linked via a photo-cleavable linker. Using PA-miR-34a, i
