Molecules 2023; 28:7602. [PMID: 38005323 PMCID: PMC10673291 DOI: 10.3390/molecules28227602] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 11/10/2023] [Accepted: 11/10/2023] [Indexed: 11/26/2023] Open
Abstract
An efficient and direct approach to pyrroles was successfully developed by employing 3-formylchromones as decarboxylative coupling partners, and facilitated by microwave irradiation. The protocol utilizes easily accessible feedstocks, a catalytic amount of DBU without any metals, resulting in high efficiency and regioselectivity. Notably, all synthesized products were evaluated against five different cancer cell lines and compound 3l selectively inhibited the proliferation of HCT116 cells with an IC50 value of 10.65 μM.

Abstract
A simple and convenient synthesis of 3-salicyloylquinoline-4-carboxylic esters has been developed through an AlCl3-catalyzed reaction of easily available Baylis-Hillman adducts from chromones and isatin-derivatives. This reaction involves esterification, cyclization and ring opening in a one-step process, and provides an efficient approach for easy access to a series of valuable salicyloylquinoline derivatives with high yields. Moreover, this protocol offers several advantages, such as availability of starting materials, economic availability, operational simplicity and mild reaction conditions.

Abstract
A mild and metal-free one-pot synthetic strategy has been developed for the construction of substituted pyrroles by employing aza-Wittig reaction from a unique and unexplored combination of chromones and phenacyl azides. This method does not compromise the diverse substitutions on both the phenacyl azides and chromones. The merits of this method are wide substrate scope, easy functionalization, short reaction time, operationally simple, and higher yields. Moreover, this method is amenable for the generation of a library of key pyrrole building blocks. A mild and metal-free one-pot synthetic strategy has been developed for the construction of substituted pyrroles by employing aza-Wittig reaction from a unique and unexplored combination of chromones and phenacyl azides.![]()

Abstract
The C-H heteroarylation of benzaldehydes with indoles and pyrroles was realized using the benziodoxolone hypervalent iodine reagents indole- and pyrroleBX. Functionalization of the aldehyde C-H bond using either an o-hydroxy or amino directing group and catalyzed by an iridium or a rhodium complex allowed the synthesis of salicyloylindoles and (2-sulfonamino)benzoylindoles, respectively, with good to excellent yields (74-98%). This new transformation could be carried out under mild conditions (rt to 40 °C) and tolerated a broad range of functionalities, such as ethers, halogens, carbonyls, or nitro groups.
