Now introduce a scientific discovery about this category.

The first metal-catalyzed C3-nucleophilic (4+3) cyclization of 2-indolylmethanols with stableortho-quinone methides has been established, which constructed indole-based seven-membered heterocycles in high yields (70 %-98 %) with regiospecificity. This reaction has tackled the challenges in exploring the C3-nucleophilicity of 2-indolylmethanols, which will contribute to the chemistry of 2-indolylmethanols, especially to metal-catalyzed cyclizations of 2-indolylmethanols. In addition, this approach will provide a useful method for constructing indole-based seven-membered heterocycles with high efficiency and regioselectivity.

Boar taint is an unpleasant odor in male pig meat, mainly caused by androstenone, skatole, and indole, which are deposited in the fat tissue. Piglet castration is the most common practice to prevent boar taint. However, castration is likely to be banished in a few years due to animal welfare concerns. Alternatives to castration, such as genetic selection, have been assessed. Androstenone and skatole have moderate to high heritability, which makes it feasible to select against these compounds. This review presents the latest results obtained on genetic selection against boar taint, on correlation with other traits, on differences in breeds, and on candidate genes related to boar taint. QTLs for androstenone and skatole have been reported mainly on chromosomes 6, 7, and 14. These chromosomes were reported to contain genes responsible for synthesis and degradation of androstenone and skatole. A myriad of work has been done to find markers or genes that can be used to select animals with lower boar taint. The selection against boar taint could decrease performance of some reproduction traits. However, a favorable response on production traits has been observed by selecting against boar taint. Selection results have shown that it is possible to reduce boar taint in few generations. In addition, modifications in diet and environment conditions could be associated with genetic selection to reduce boar taint. Nevertheless, costs to measure and select against boar taint should be rewarded with incentives from the market; otherwise, it would be difficult to implement genetic selection.

This review article summarizes the fundamental synthetic procedures aimed at the preparation of unsymmetrical bisindolylmethanes that have appeared in the literature since 2010. To this goal, reactive electrophilic indole-containing intermediates are mostly generated from indolylmethanols, indolylmethanamines, and indolylmethanthio derivatives and then made to react with simple or functionalized indoles. The asymmetric synthesis of bisindolylmethanes can be also achieved under chiral-catalyzed conditions. 1 Introduction 2 Direct Three-Component Coupling 3 Reaction of Indolylmethanols 4 Reaction of Indolylmethanamine Derivatives 5 Reaction of 3-Vinylindoles 6 Reaction of indolylmethanthio Derivatives 7 Bisindolylmethanes by Ring Closure of Alkyne Derivatives 8 Miscellaneous Methods 9 Conclusion

The total syntheses of dimeric indole alkaloids, haplophytine, and T988s are described. These dimeric compounds comprising two structurally different indole units are ubiquitous in nature, and many possess pharmaceutically important activities. To realize an efficient chemical synthesis of these dimeric indole alkaloids, the establishment of convergent synthetic strategies and development of new coupling methods are indispensable. The linkage of two highly functionalized units at a late stage of the synthesis frequently induces synthetic problems such as chemoselectivity and steric repulsion. Moreover, although transition metal-catalyzed reactions are usually an effective method for the cross-coupling of two units, the application of these cross-coupling reactions to bond formation involving a sterically hindered C(sp(3)) is often difficult. Thus, even with precise modern synthetic methods, it is currently difficult to realize convergent syntheses of dimeric indole alkaloids possessing a quaternary carbon linking two units. To combat these synthetic problems, we developed a synthetic method to link two indole units using an Ag-mediated nucleophilic substitution reaction. In this review, we provide a detailed discussion of convergent synthetic strategies and coupling methods for dimeric indole alkaloids.
