The Diels-Alder approach for the synthesis of tetralin-based α-amino acid derivatives and their modification by the Suzuki-Miyaura cross-coupling reaction

Tetralin-based a-amino acid (AAA) is a constrained analogue of phenylalanine (Phe) and is used extensively in the design and synthesis of a variety of bioactive peptides. Due to the nonavailability of simple synthetic methods to deliver complex cyclic AAA

Novel fullerene-based porous materials constructed by a solvent knitting strategy

Here we choose a dihydronaphthyl-functionalized C60 fullerene as a building block and utilize a novel solvent knitting strategy based on Friedel-Crafts alkylation reaction to construct two kinds of novel porous materials by using dichloromethane (DCM) and 1,2-dichloroethane (DCE) as solvents and external crosslinkers. The resulting porous materials show relatively high apparent BET surface areas and gas uptake abilities.

Diels-Alder approach to tetralin-based constrained α-amino acid derivatives

Tetralin-based constrained α-amino acid derivatives were prepared via [4+2]-cycloaddition reaction as a key step. Here sultine is used as a latent diene and 2-acetamidoacrylate serves as a dienophile component. (C) 2000 Elsevier Science Ltd. All rights reserved.

Benzosulfones as photochemically activated sulfur dioxide (SO2) donors

Sulfur dioxide (SO2) is a gaseous environmental pollutant which is routinely used in industry as a preservative and antimicrobial. Recent data suggests that SO2 may have value as a therapeutic agent. However, due to its gaseous nature, localizing SO2 generation is challenging. Herein, various 1,3-dihydrobenzo[c]thiophene 2,2-dioxides (benzosulfones) were prepared as candidates for photochemically activated sulfur dioxide (SO2) generation. These compounds were found to be stable in buffer but were photolysed upon irradiation with UV light to generate SO2. Our data indicates that photolysis of benzosulfones depends on substituents, and that the presence of electron donating groups results in an enhanced yield of SO2. This journal is

Dihydronaphthyl-based [60]fullerene bisadducts for efficient and stable polymer solar cells

Dihydronaphthyl-based [60]fullerene bisadduct derivative, NC 60BA, was synthesized at mild temperature in high yield. NC 60BA not only possesses a LUMO energy level 0.16 eV higher than PC61BM but also has amorphous nature that can overcome thermal-driven crystallization. The fabricated P3HT:NC60BA-based polymer solar cells exhibit superior photovoltaic performance and thermal stability compared to PC61BM-based devices under the same conditions.

Sigma-1 ligands: Tic-hydantoin as a key pharmacophore

Sigma-1 receptors are involved in numerous pathological dysfunctions and the synthesis of selective ligands is of interest. We identified a fused tetrahydroisoquinoline-hydantoin (Tic-hydantoin) structure with high affinity and selectivity for these receptors. We report here our efforts towards the pharmacomodulation of this substructure, the synthesis of 9 analogs with stereochemistry inversion, opening of isoquinoline ring, removal of isoquinoline nitrogen, replacement of isoquinoline by pyridine, of Tic-hydantoin moiety by quinazolinedione heterocycle. All these analogs provided a loss in the affinity for the sigma-1 receptor. The present work underlines the real importance of the Tic-hydantoin moiety for the obtainment of high affinity ligands.
