Exploring the Boundaries of “practical”: De Novo Syntheses of Complex Natural Product-Based Drug Candidates

This review examines the state of the art in synthesis as it relates to the building of complex architectures on scales sufficient to drive human drug trials. We focus on the relatively few instances in which a natural-product-based development candidate has been manufactured de novo, rather than semisynthetically. This summary provides a view of the strengths and weaknesses of current technologies, provides perspective on what one might consider a practical contribution, and hints at directions the field might take in the future.

Synthesis of furo[3,2-g]chromones under microwave irradiation and their antitumor activity evaluation

A series of furo[3,2-g]chromone derivatives were synthesized via the reaction of furochromone carbaldehyde 1 with amines 3a-d and thioglycolic acid to give thiazolidinones 4a-d. The later react with benzaldehyde/thiourea or hydroxylamine and DMF-DMA in glacial acetic acid to give thiazolopyrimidines 5a-d or thiazoloisoxazoles 6a-d, respectively. Also, the synthesis of alpha-aminophosphonates via the one-pot reaction of 1 and amines 3a,b were trapped by dialkylphosphites 7a-c afforded the corresponding alpha-aminophosphonates 8a-f. Applying hexaalkyltriamidophosphites 9a,b to 1 gives alkylidenephosphorane ylides 11a,b in an open structure form. In the present investigation, the in vitro inhibition capacity of compounds (4a, 4c, 5b, 5c, 6b-d, 8a-f, and 11a) was screened in three human cancer cell lines HCT-116, MCF-7, and HepG2. The anticancer activity results revealed that 8b and 8e had more potent cytotoxic inhibition activity against HCT-116 cell line; however, all the tested compounds had obviously less cytotoxic activity against MCF-7 cell line, while 5b, 5c, and 6d were potent against HepG2 cell line compared with that of doxorubicin.

Mild and efficient palladium-catalyzed direct trifluoroethylation of aromatic systems by C-H activation

The introduction of trifluoroalkyl groups into aromatic molecules is an important transformation in the field of organic and medicinal chemistry. However, the direct installation of fluoroalkyl groups onto aromatic molecules still represents a challenging and highly demanding synthetic task. Herein, a simple trifluoroethylation process that relies on the palladium-catalyzed C-H activation of aromatic compounds is described. With the utilization of a highly active trifluoroethyl(mesityl)iodonium salt, the developed catalytic method enables the first highly efficient and selective trifluoroethylation of aromatic compounds. The robust catalytic procedure provides the desired products in up to 95 % yield at 25 C in 1.5 to 3 hours and tolerates a broad range of functional groups. The utilization of hypervalent reagents opens new synthetic possibilities for direct alkylations and fluoroalkylations in the field of transition-metal-catalyzed C-H activation.

Golden Jubilee for Scorpionates. Recent Advances in Organometallic Chemistry and Their Role in Catalysis

This review aims to describe some recent trends in organometallic complexes containing scorpionate ligands. Particular attention will be paid to the ligands structure, reagents, and methods developed during the past decade and contextualize them within the broad field of organometallic chemistry. In fact, novel ligand design has itself become a fundamental part of most organometallic researches and many catalytic conversions have been attained by subtle modification of the metal environment through a careful choice of the ancillary ligands. This review, which is necessarily limited in scope, reports the organometallic complexes with azolylborate and azolylalkane ligands from 2008 until today and it is organized according to the metal center.

Synthesis and biological evaluation of coumarin based isoxazoles, pyrimidinthiones and pyrimidin-2-ones

The titled compounds (6?a?k), (7?a?k) and (8?a?k) were synthesized from chalcones (5a?k) having coumarin moiety. Cyclization of chalcones (5a?k) with hydroxyl amine hydrochloride, thiourea and urea resulted in corresponding isoxazoles (6?a?k), pyrimidinthiones (7?a?k) and pyrimidin-2-ones (8?a?k). Structures of newly synthesized compounds were established on the basis of their elemental analysis, IR, 1H NMR, 13C NMR, and mass spectral data. The synthesized analogs were evaluated for their antimycobacterial activity and antimicrobial activity against eight bacteria (Staphylococcus aureus, Bacillus cereus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Salmonella typhi, Proteus vulgaris, and Shigella flexneri) and four fungi (Aspergillus niger, Candida albicans, Aspergillus fumigatus, and Aspergillus clavatus).

146. 15N-NMR Spectra of Azoles with Two Heteroatoms

The 15N-NMR spctra of azoles, with natural isotope abundance, have been measured under different experimental conditions, and chemical shifts are reported for imidazoles, pyrazoles, oxazoles, isoxazoles, thiazoles and isothiazoles.General trends of substituent effects in this heterocyclic series are discussed based on the data of 67 substituted azoles, dihydro- and tetrahydroazoles. 15N, 1H spin-coupling constants have been determined from spectra obtained by (1H) -> 15N polarizationtransfer experiments, i.e. an application of INEPT and DEPT pulse sequences.Two-bond and three-bond coupling constants are fully assigned and are discussed in terms of the specific pathways in azoles.The potential of structural applications of the new data is illustrated for isomeric nitro-imidazoles and highly-substituted pyrazoles, and in the case of ring-chain tautomerism of 2-substituted tetrahydrooxazoles.
