5-Carbapterocarpens, one of them displaying estrogenic activity, were prepared from alpha-aryltetralones in high yields through a one-pot, BBr3-promoted O-demethylation and cyclization sequence. The key alpha-aryltetralone intermediates were obtained by direct alpha-arylation of tetralones with o-alkoxybromoarenes in the presence of Pd2(dba)3 (2.5 mol-%) and tBu3PHBF4 (10 mol-%) as catalysts, together with 2.5 equiv. of KOH in dioxane/H2O (4:1), under microwave irradiation conditions (80 W, 100 C, 40 min), leading to alpha-monoaryltetralones in good yields.

A polyaromatic tube with a subnanometer-sized cavity was efficiently prepared on a gram-scale through the stereo-controlled cyclotrimerization of a diphenylanthracene derivative as a key step. The facile exterior alkylation of the polyaromatic framework leads to a moderately fluorescent tube (R=-OC10H21; PhiF=20 %) in the solid state. The emission intensity of the solid-state alkyl-substituted tube is remarkably enhanced upon heating (up to 1.6 times, PhiF=31 %) as well as doping with fluorescent dyes (up to 4.2 times, PhiF=83 %) through efficient energy transfer.

A sequential multicomponent coupling approach is a powerful method for the construction of combinatorial libraries because structurally complex and diverse molecules can be synthesized from simple materials in short steps. In this paper, an efficient synthesis of nickel(II) complexes with N-aryl-2-amino phenols via a sequential three-step coupling approach is described, for potential use in nonlinear optical materials, bioinspired catalytic systems, and near-infrared absorbing filters. Seventeen N-aryl-2-amino phenolates were successfully synthesized in high yields based on the coupling of 3,5-di-tert-butylbenzene-1,2-diol with a pivotal aromatic scaffold, 4-bromo-2-iodo-aniline, followed by sequential Suzuki-Miyaura coupling with aryl boronates. A total of 16 analytically pure nickel(II) complexes with N-aryl-2-amino phenolates were obtained from 17 complexation trials. The procedure allowed us to assemble 4 components in high yields without protection, deprotection, oxidation or reduction steps. Various building blocks that included electron-donating, electron-withdrawing, and basic were used, and readily available, nontoxic and environmentally benign substrates and reagents were employed with no generation of toxic compounds. No strict anhydrous or degassed conditions were required. Absorption spectroscopic measurement of the synthesized nickel(II) complexes revealed that the ortho-substituent Ar 1 exerted more influence on the absorption wavelength of the complexes than the para-substituent Ar2. On the other hand, both substituents Ar1 and Ar2 influenced the molar absorptivity values. These observations should be useful for the design of new and useful nickel(II) complexes as near-infrared chromophores.

Total synthesis of dictyodendrins B and e

The concise synthesis of the novel telomerase inhibitors dictyodendrins B and E was completed in only 9 and 11 steps (longest linear sequence). The highly convergent strategy employed a palladium-catalyzed Larock indole synthesis and a palladium-mediated one-pot consecutive Buchwald-Hartwig amination/C-H activation reaction as key steps. The present synthesis exhibits respectable levels of atom-, redox-, and step-economy.

N,N-Di-para-methylthiophenylamine-Substituted (2-Ethylhexyl)-9H-Carbazole: A Simple, Dopant-Free Hole-Transporting Material for Planar Perovskite Solar Cells

A dopant-free hole-transporting material (HTM), with (2-ethylhexyl)-9H-carbazole as core and N,N-di-p-methylthiophenylamine as end groups, termed CMT, has been designed and synthesized by a simple method. For the first time, four methylthiol groups have been introduced, rather than methoxy groups, at the para position of the diphenylamine. Under AM 1.5 illumination at 100 mW cm-2, perovskite solar cells based on CH3NH3PbI3 with pristine CMT as the HTM achieved a power conversion efficiency of 13.05%, with a short-circuit current density of 21.82 mA cm-2, an open-circuit voltage (VOC) of 1.03 V, and a fill factor of 58.23%. The value of VOC is comparable to that of the device based on 2,2?,7,7?-tetrakis(N,N-di-para-methoxy-phenylamino)-9,9?-spirobifluorene, which was 1.02 V.

A new organogelator SYW without common auxiliary groups was synthesized and characterized, and its gelation properties were systematically studied. SYW preferably gelatinized from aromatic solvents, and in these cases formed stable organogels. The emission of light from SYW was very weak in solution but significantly stronger in the gel state, i.e., showing typical gelation-induced emission enhancement (GIEE). In particular, the xerogel film showed bright yellow emission and could be used for detecting trifluoroacetic acid (TFA) vapor. The fibrous film exhibited high sensitivity to this vapor, and the detection limit was estimated to be quite low, at 3.2 ppb. Reports of organogeltors lacking normal auxiliary groups yet still able to form gels and detect certain species have been rare, so the current work on SYW enriches the study of organogels.
