The Xanthate Route to Indolines, Indoles, and their Aza Congeners

Convergent routes to a variety of indolines, indoles, oxindoles, and their aza analogues involving radical additions of xanthates are described. Three approaches are summarized. The first is the least general and relies on the generation of aryl or heteroaryl radicals starting from diazonium salts. The second involves radical addition toN-allylanilines followed by ring-closure onto the aromatic core. A large variety of indolines and azaindolines can thus be obtained and, in many cases, converted into the corresponding indoles and azaindoles by various methods. The synthesis of novel fluoroazaindolines and fluoroazaindoles by a rare homolyticipso-substitution of fluorine atoms is particularly noteworthy. The last approach hinges on the direct modification of indoles by radical addition to the pyrrole subunit of the indole nucleus. Application of this methodology to the total synthesis of melatonin and the alkaloids mersicarpine, caulerpine, and the pentacyclic skeleton of tronocarpine is briefly discussed. Most of the compounds described herein would be difficult to obtain by more traditional routes.

Dual Catalytic Synthesis of Antiviral Compounds Based on Metallocarbene-Azide Cascade Chemistry

Aryl azides trap ortho-metallocarbene intermediates to generate indolenones possessing a reactive C-acylimine moiety, which can react with added indole nucleophiles to afford the 2-(3-indolyl)indolin-3-one scaffold found in the antiviral natural product isatisine A. This overall process occurs through a dual catalytic sequence at room temperature. Redox activation of the Cu(OTf)(2) precatalyst by indole results in catalytically competent Cu(I) required for azide-metal-locarbene coupling. The Bronsted acid that is also formed from Cu(OTf)(2) reduction is responsible for catalysis of the C-C bond-forming indole addition step. This modular, procedurally simple method allows for rapid assembly of bis(indole) libraries, several of which proved to have anti-infective activity against respiratory syncytial virus and Zika virus.

Genome-wide characterization and expression analyses of the auxin/indole-3-acetic acid (Aux/IAA) gene family in apple (Malus domestica)

Auxin is a necessary phytohormone for fruit development, accompanying the whole process of fruit growth and development. The Aux/IAA gene family is one of the early auxin-responsive gene families. At present, there were few reports involved in Aux/IAA genes in the fruit, especially in apple. In our study, we identified 42 MdAux/IAAs, phylogenetic analysis showed that Aux/IAA proteins from apple, tomato, and strawberry were clustered into 5 groups, 42 MdAux/IAAs randomly distributed on 13 chromosomes. Additionally, a comprehensive analysis of Aux/IAA gene family was completed, including gene structures, conserved motifs, phylogenetic analysis, chromosome mapping, orthologous identification, selection pressure analyses, synteny analysis, and protein interaction. We also tested the expression of MdAux/IAAs in different tissues and fruit development stages using quantitative reverse transcription-polymerase chain reaction (qRT-PCR), we found that the most members of Aux/IAA showed higher expression in seeds compared within stem and leaves, indicating they may play a role in regulating fruit development. We also declared that the expression of Aux/IAA gene was not consistent in the pericarp and seeds at the same developmental stage, 3 MdAux/IAAs of the pericarp were upregulated over 20 fold at 90 d and 5 MdAux/IAAs of the seeds were upregulated over 40-fold at 90 d. It was MdAux/IAA23 that showed extreme up-regulated expression in both pericarp and seeds. This study proved that the Aux/IAA gene families may perform a different function in apple fruit development and ripening, more importantly, it provided a foundation for further exploring the biological function of these MdAux/IAAs.

A novel and efficient approach for the highly selective C-2 difluoromethylation of indole derivatives was developed by using sodium difluoromethylsulfinate (HCF2SO2Na) as the source of difluoromethyl groups and a Cu(ii) complex as the catalyst. Various substrates were well tolerated in this transformation and the desired products were obtained in moderate to good yields. Moreover, the late-stage C-2 difluoromethylation of bioactive molecules containing an indole ring was achieved in good yields.

Computational design of an intramolecular photocyclization reaction with state-selective reactivity: a strategy for indole synthesis

The development of a convenient and environmentally friendly indole synthesis method is of great methodological and pharmaceutical interest. In this work, we discovered an intramolecular photocyclization of carbonyls and tertiary amines for indole synthesis without relying on photocatalysts. A wide range of functional indoles were prepared with moderate to excellent yields under mild reaction conditions. Furthermore, our extensive quantum mechanics (QM) calculations and synthesis experiments revealed the ‘state-selective reactivity’ feature of this reaction, and different substrate types can achieve different yields through this feature. This new insight into the interplay between the ‘state-selective reactivity’ and the yields emphasizes its importance and gives guidance regarding the ‘state-selective reactivity’ for the high yield of various indole derivatives.
