Abstract
Two pairs of new salicylaldehyde derivative enantiomers, salicylaldehydiums A and B (1 and 2), along with five known analogues were isolated and identified from a marine-derived fungus Eurotium sp. SCSIO F452. Their structures and absolute configuration were determined by extensive spectroscopic analysis and electronic circular dichroism (ECD) calculations. All the new optical pure enantiomers [(+)-1, (-)-1, (+)-2, (-)-2] were evaluated for their cytotoxic and antioxidative activities. Compound (-)-1 exhibited weak cytotoxic activity.

Khademi Z, Nikoofar K. Applications of alkyl orthoesters as valuable substrates in organic transformations, focusing on reaction media. RSC Adv 2020; 10:30314-30397. [PMID: 35559005 PMCID: PMC9092620 DOI: 10.1039/d0ra05276k] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/16/2020] [Accepted: 07/27/2020] [Indexed: 02/01/2023] Open
Abstract
In this review we focus on applications of alkyl orthoesters as valuable and efficient substrates to perform various classes of two-component and multi-component organic reactions. The article has classified them according to two aspects, which are: (i) a focus on the reaction medium (solvent-free conditions, aqueous media, and organic solvents); and (ii) an examination of product structures. Reaction accomplishment under solvent-free conditions is an eco-friendly process with the absence of volatile toxic solvents, which puts it in line with green chemistry goals. Water is an interesting choice in organic transformations due to its inexpensiveness and safety. The authors hope their assessment will help chemists to attain new approaches for utilizing alkyl orthoesters in various organic synthetic methods. The review covers the corresponding literature up to the beginning of 2020.

Abstract
A new route to the chromene ring system has been developed which involves the reaction of an α,β-unsaturated Fischer carbene complex of chromium with a propargyl ether bearing an alkenyl group on the propargylic carbon. This transformation involves a cascade of reactions that begins with a benzannulation reaction and is followed by the formation of an o-quinone methide, and finally results in the emergence of a chromene upon an electrocyclization. This reaction was extended to provide access by employing an aryl carbene complex. This constitutes the first synthesis of chromenes in which both rings of the chromene system are generated in a single step and is highlighted in the synthesis of lapachenole and vitamin E.

Abstract
We recently reported that 3,3-dimethyl-3H-benzofuro[3,2,f][1]-benzopyran and its hydrogenated analogue are selective in vitro inhibitors of mycobacterial growth. However, their lack of in vivo activity on a murine model of Mycobacterium tuberculosis infection due to their poor bioavailability led to a structure-activity relationship investigation. We wish to report here the preparation of some structural analogues along with their biological effect on the growth of Mycobacterium smegmatis, M. tuberculosis, as well as on VERO cells for the most active compound.

Abstract
Tuberculosis is today amongst the worldwide health threats. As resistant strains of Mycobacterium tuberculosis have slowly emerged, treatment failure is too often a fact, especially in countries lacking the necessary health care organisation to provide the long and costly treatment adapted to patients. Because of lack of treatment or lack of adapted treatment, at least two million people will die of tuberculosis this year. Due to this concern, this infectious disease was the focus of renewed scientific interest in the last decade. Regimens were optimized and much was learnt on the mechanisms of action of the antituberculosis drugs used. Moreover, the quest for original drugs overcoming some of the problems of current regimens also became the focus of research programmes and many new series of M. tuberculosis growth inhibitors were reported. This review presents the drugs currently used in antituberculosis treatments and the most advanced compounds undergoing clinical trials. We then provide a description of their mechanism of action along with other series of inhibitors known to act on related biochemical targets. This is followed by other inhibitors of M. tuberculosis growth, including recently reported compounds devoid of a reported mechanism of action.
