Abstract
A green approach for the synthesis of electrophilic alkenes has been developed via Knoevenagel condensation between active methylene compounds and carbonyl compounds using Mg powder under aqueous conditions. In this strategy, Mg(OH)2 acts as a catalyst, which was generated in situ by the reaction between metallic Mg (20 mol %) and water. Mg was found to be an efficient, nontoxic, and inexpensive metal catalyst system for producing a range of electrophilic alkenes in excellent yields (≤98%). A gram-scale synthesis of electrophilic alkenes has been developed, and Mg metal was recovered and recycled up to three times without an appreciable loss of catalytic activity. A catalytic cycle was proposed, and the reaction mechanism was investigated using density functional theory. The key steps are enolization of ethyl cyanoacetate, C-C bond formation, and then regeneration of the catalyst via metathesis with H2O. The overall reaction occurs easily with a maximum ΔG°⧧ value of 7.9 kcal/mol for the rate-determining C-C bond formation step. Our protocol has several advantages and can be further extended to one-pot sequential Knoevenagel condensation and Michael addition, and one-pot sequential Knoevenagel condensation and chemoselective reduction can be used for the synthesis of valuable precursors of pharmaceutical products under green and aqueous conditions.

Abstract
Multicomponent reactions 9i.e., those that engage three or more starting materials to form a product that contains significant fragments of all of them), have been widely employed in the construction of compound libraries, especially in the context of diversity-oriented synthesis. While relatively less exploited, their use in target-oriented synthesis offers significant advantages in terms of synthetic efficiency. This review provides a critical summary of the use of multicomponent reactions for the preparation of active pharmaceutical principles.

Abstract
![]()
Multicomponent
Petasis reaction has been widely applied for the synthesis of functionalized
amine building blocks and biologically active compounds. Employing
primary aromatic amines that are not typical reactive substrates contributes
to expand the application scope of the Petasis reaction. In this study,
we demonstrated the synthesis of functionalized 2-aminothiophenes
using Gewald-reaction-derived 2-aminothiophenes as the amine substrates,
whose low reactivity in the Petasis reaction was overcome using hexafluoro-2-propanol
as the solvent in a mild condition. The obtained Petasis products
are amenable for further transformations owing to the presence of
multiple functional handles. A following intramolecular cyclization
of selected Petasis products afforded substituted tricyclic heterocycles
that incorporate a pharmaceutically interesting thienodiazepine moiety.

Abstract
The synthesis of sulfur heterocycles via the construction of C–S bonds has received considerable attention due to their biological value and extensive pharmaceutical application. While diverse sulfurating agents have been developed over the past few decades, in this regard, elemental sulfur, with advantages of low toxicity, odorless nature and chemical stability, has great potential for the construction of diverse sulfur heterocycles through its direct incorporation into the target molecules in a concise way. Direct functionalization of inert C–H bonds can shorten the number of reaction steps and minimize the amount of waste formed. Hence, heteroannulations via direct C–H sulfuration is considered to be an attractive strategy for the synthesis of sulfur heterocycles. In the last few years, a vast array of concise systems have been reported for the synthesis of some valuable sulfur heterocycles such as thiophenes, thienoindoles, thienothiazoles, thiazoles, benzothiazoles, and thiadiazoles through direct C–H sulfuration/annulations with elemental sulfur. These are discussed in detail in this review.1 Introduction2 Thiophenes3 Thienoindoles4 Thienothiazoles5 Other Fused Thiophenes6 Thiazoles7 Benzothiazoles8 Thiadiazoles9 Others10 Summary and Outlook

Abstract
Multicomponent reactions (MCRs) are composed of three or more reagents in which the final
product has all or most of the carbon atoms from its starting materials. These reactions represent, in the
medicinal chemistry context, great potential in the research for new bioactive compounds, since their products
can present great structural complexity. The aim of this review is to present the main multicomponent reactions
since the original report by Strecker in 1850 from nowadays, covering their evolution, highlighting their
significance in the discovery of new bioactive compounds. The use of MCRs is, indeed, a growing field of
interest in the synthesis of bioactive compounds and approved drugs, with several examples of commerciallyavailable
drugs that are (or can be) obtained through these protocols.

Abstract
A Na2HPO4-catalyzed four-component reaction between a ketone, malononitrile, S8 and formamide has been realized for the first time. This reaction provides a concise approach to thieno[2,3-d]pyrimidin-4-amines, previously requiring 5 steps. The utility of this reaction was validated by preparing a multi-targeted kinase inhibitor and an inhibitor of the NRF2 pathway with excellent atom- and step-economy.

2-Aminothiophene scaffolds: Diverse biological and pharmacological attributes in medicinal chemistry. Eur J Med Chem 2017; 140:465-493. [PMID: 28987607 DOI: 10.1016/j.ejmech.2017.09.039] [Citation(s) in RCA: 59] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2017] [Revised: 09/02/2017] [Accepted: 09/19/2017] [Indexed: 12/30/2022]
Abstract
2-Aminothiophenes are important five-membered heterocyclic building blocks in organic synthesis, and the chemistry of these small molecules is still developing based on the discovery of cyclization by Gewald. Another attractive feature of 2-aminothiophene scaffolds is their ability to act as synthons for the synthesis of biological active thiophene-containing heterocycles, conjugates and hybrids. Currently, the biological actions of 2-aminothiophenes or their 2-N-substituted analogues are still being investigated because of their various mechanisms of action (e.g., pharmacophore and pharmacokinetic properties). Likewise, the 2-aminothiophene family is used as diverse promising selective inhibitors, receptors, and modulators in medicinal chemistry, and these compounds even exhibit effective pharmacological properties in the various clinical phases of appropriate diseases. In this review, major biological and pharmacological reports on 2-aminothiophenes and related compounds have been highlighted; most perspective drug-candidate hits were selected for discussion and described, along with additional synthetic pathways. In addition, we focused on the literature dedicated to 2-aminothiophenes and 2-N-substituted derivatives, which have been published from 2010 to 2017.
