Abstract
The field of cascade cyclization for the construction of 1,4-dihydropyridines (1,4-DHPs) has been continuously expanding during the last decades because of their broad-spectrum biological and synthetic importance. To date, many methods have been developed, mainly including the Hantzsch reaction, Hantzsch-like reaction and newly developed cascade cyclization, in which various synthons have been successively developed as C4 sources of 1,4-DHPs. This review presents the cascade cyclization synthesis strategy for the construction of 1,4-DHPs according to various C4 sources from carbonyl compounds, alkenyl fragments, alcohols, aliphatic amines, glycines and other C4 sources.

Abstract
Indoles and their derivatives have dominated a significant proportion of nitrogen-containing heterocyclic compounds and play an essential role in synthetic and medicinal chemistry, pesticides, and advanced materials. Compared with conventional synthetic strategies, direct functionalization of indoles provides straightforward access to construct diverse indole scaffolds. As we enter an era emphasizing green and sustainable chemistry, utilizing environment-friendly solvents represented by water demonstrates great potential in synthesizing valuable indole derivatives. This review aims to depict the critical aspects of aqueous-mediated indoles functionalization over the past decade and discusses the future challenges and prospects in this fast-growing field. For the convenience of readers, this review is classified into three parts according to the bonding modes (C-C, C-N, and C-S bonds), which focus on the diversity of indole derivatives, the prominent role of water in the chemical process, and the types of catalyst systems and mechanisms. We hope this review can promote the sustainable development of the direct functionalization of indoles and their derivatives and the discovery of novel and practical organic methods in aqueous phase.

Abstract
Multicomponent reactions (MCRs) are a valuable tool in diversity-oriented synthesis. Its application to privileged structures is gaining relevance in the fields of organic and medicinal chemistry. Isatin, due to its unique reactivity, can undergo different MCRs, affording multiple interesting scaffolds, namely oxindole-derivatives (including spirooxindoles, bis-oxindoles and 3,3-disubstituted oxindoles) and even, under certain conditions, ring-opening reactions occur that leads to other heterocyclic compounds. Over the past few years, new methodologies have been described for the application of this important and easily available starting material in MCRs. In this review, we explore these novelties, displaying them according to the structure of the final products obtained.

Abstract
Reactions in water have demonstrated numerous surprising results. The effects
of water in these reactions may include significant physical and chemical interactions with
the substrates and catalysts through polar effects and hydrogen bonding ability. In some
instances, water is also able to interact with the intermediates of reactions and possibly
with the transition states of chemical processes. Organic synthesis in water encourages the
researchers to follow the principles of green chemistry. Among heterocyclic compounds,
quinoline scaffold has become an important motif for the development of new
drugs. They are widely found in pharmaceuticals as well as in agrochemical industry. Over
the last few decades, numerous reports have been documented to access quinoline derivatives
with structural diversity, either by new annulation or by ring functionalization. This review summarizes an
overview of the synthesis and functionalisation of quinoline scaffolds in an aqueous medium. This method may
encourage researchers to adopt green chemistry and to apply these environmentally safe methods in designing
important heterocyclic cores.

Abstract
The challenge of prebiotic chemistry is to
trace the syntheses of life’s key building blocks
from a handful of primordial substrates. Here we
report a forward-synthesis algorithm that
generates a full network of prebiotic chemical
reactions accessible from these substrates under
generally accepted conditions. This network
contains both reported and previously unidentified
routes to biotic targets, as well as plausible
syntheses of abiotic molecules. It also exhibits
three forms of nontrivial chemical emergence, as
the molecules within the network can act as
catalysts of downstream reaction types; form
functional chemical systems, including
self-regenerating cycles; and produce surfactants
relevant to primitive forms of biological
compartmentalization. To support these claims,
computer-predicted, prebiotic syntheses of several
biotic molecules as well as a multistep,
self-regenerative cycle of iminodiacetic acid were
validated by experiment.

Abstract
A highly efficient protocol for copper-catalyzed thio-alkynylation of enaminone-based thiocyanates with terminal alkynes under mild conditions has been developed. This scalable amino group-directed thio-alkynylation proceeds in the open air with a broad substrate scope and an excellent yield. The demonstrated synthetic transformation creates the opportunity for a wide variety of sulfur-containing useful materials. Gram-scale synthesis and further synthetic transformations of alkynyl sulfides highlight the potential utility of the method.
