Recent advances in organocatalytic atroposelective reactions
Beilstein J. Org. Chem. 2025, 21, 55–121, doi:10.3762/bjoc.21.6
- were achieved. 2-Nitrosonaphthalenes 211 could also react with 2-naphthols 214 in the presence of CPA C49 to form axially chiral binaphthyls 215 and finally after hydrogenation atroposelective NOBINs 216. This reaction yielded products in mostly moderate amounts with good levels of enantiomeric purity
4,6-Diaryl-5,5-difluoro-1,3-dioxanes as chiral dopants for liquid crystal compositions
Beilstein J. Org. Chem. 2024, 20, 2940–2945, doi:10.3762/bjoc.20.246
- range of chiral, twisted molecules such as binaphthyls [23][24][25], biphenyls [26][27], TADDOLs [16][17] and 1,2-diphenylethane-1,2-diol [28] to reveal possible relationships between the molecular structure of chiral dopants and their HTP value. However, quantitative structure–property relationships
Asymmetric organocatalyzed synthesis of coumarin derivatives
Beilstein J. Org. Chem. 2021, 17, 1952–1980, doi:10.3762/bjoc.17.128
- of 2-hydroxycinnamaldehydes is important for the success of the employed catalytic system. Finally, but not least, the phase-transfer chiral organocatalysts have also been highly explored [72][73]. Most of the PTCs are based on the skeletons of cinchona alkaloids and chiral binaphthyls, though, more
The biomimetic synthesis of balsaminone A and ellagic acid via oxidative dimerization
Beilstein J. Org. Chem. 2020, 16, 2026–2031, doi:10.3762/bjoc.16.169
- synthesized through the oxidation of lawsone (6), in the presence of sodium persulfate, followed by methylation [25]. The cyclization of binaphthyl 16 was then attempted taking into consideration the photolytic cyclization of binaphthyls to form pentacyclic furan derivatives [8][18][22]. However, the
Further exploration of the heterocyclic diversity accessible from the allylation chemistry of indigo
Beilstein J. Org. Chem. 2015, 11, 481–492, doi:10.3762/bjoc.11.54
- ' reagent. This is not unexpected as there are reports of ruthenium-based species catalysing Claisen rearrangements [7] including a similar RCM–Claisen sequence in 2,2'-bis(allyloxy)-1,1'-binaphthyls and O,O'-(but-2-en-1,4-diyl) binaphthols [12][13]. Additionally, examples of C2 to C3 Claisen rearrangement
Self-assembly of metallosupramolecular rhombi from chiral concave 9,9’-spirobifluorene-derived bis(pyridine) ligands
Beilstein J. Org. Chem. 2014, 10, 432–441, doi:10.3762/bjoc.10.40
- from other rigid scaffolds such as Tröger's bases or 2,2'-dihydroxy-1,1'-binaphthyls this suggests that the bend angle of the V-shaped ligands seems to be a crucial general factor that has to be adjusted carefully to obtain (high-fidelity) self-sorting. Angles of more than 105° cause an unfavourable

- and Enterococci (VRE, VSE), and against Staphylococcus epidermidis. Keywords: antibacterials; binaphthyls; cationic peptides; peptides; resistance; VISA; VRE; Introduction Among the most pressing challenges in current healthcare is the resistance of bacterial human pathogenic organisms to
Synthesis and anion recognition properties of shape-persistent binaphthyl-containing chiral macrocyclic amides
Beilstein J. Org. Chem. 2012, 8, 967–976, doi:10.3762/bjoc.8.109
- chiral binol scaffolds, which incorporate either methoxy or acetoxy functionalities in the 2,2' positions and carboxylic functionalities in the external 3,3' positions, were used as the source of chirality. Two of these binaphthyls are joined through amidation reactions using rigid diaryl amines of
Synthesis of 5-(2-methoxy-1-naphthyl)- and 5-[2-(methoxymethyl)-1-naphthyl]-11H-benzo[b]fluorene as 2,2'-disubstituted 1,1'-binaphthyls via benzannulated enyne–allenes
Beilstein J. Org. Chem. 2011, 7, 496–502, doi:10.3762/bjoc.7.58
- '-disubstituted 1,1'-binaphthyls with the newly constructed benzofluorenyl group serving as a naphthyl moiety. Keywords: benzannulated enediynyl alcohols; benzannulated enyne–allenes; 2,2'-disubstituted 1,1'-binaphthyls; 5-(1-naphthyl)-11H-benzo[b]fluorenes; Schmittel cascade cyclizations; Introduction
- -(methoxymethyl)-1-naphthyl group at one of the alkynyl termini of the benzannulated enediyne system, the resulting naphthyl-substituted benzo[b]fluorenes could be regarded as 2,2'-disubstituted 1,1'-binaphthyls with two additional substituents at the 3 and 4 positions. The versatility of 1,1'-binaphthyl-2,2
- '-diol (BINOL) and BINOL derivatives as reagents in asymmetric synthesis has stimulated the development of new synthetic methods for 2,2'-disubstituted 1,1'-binaphthyls [8][9][10][11][12][13][14][15][16]. However, the great majority of the reported methods involved coupling of two properly substituted 1
Chiral amplification in a cyanobiphenyl nematic liquid crystal doped with helicene-like derivatives
Beilstein J. Org. Chem. 2009, 5, No. 50, doi:10.3762/bjoc.5.50
- highly flexible substituents. Not surprisingly, taking into account molecular shape, the orientational behavior of 1–8 derivatives is analogous to that of bridged binaphthyls and also the helical twisting power can be interpreted in a similar way: the outcome is that pseudo-P dopants induce a right
