Abstract
A sequential post-transformation of Ugi four-component reaction/nucleophilic substitution was developed for the synthesis of spiro-β-lactam-pyrroloquinolines. This method involves the Ugi-4CR of 2-chloro-3-formyl quinolines 1a-h, amines 2a-d, 2-chloroacetic acid 3, and isocyanides 4a, 4b for the synthesis of versatile precursors 5a-v. The Ugi adducts were intramolecularly cyclized under basic conditions through the sequential nucleophilic aromatic substitution (SNAr)/second-order nucleophilic substitution (SN2) reaction to give spiro-β-lactam-pyrroloquinoline scaffolds 6a-t. This approach is an efficient method for the synthesis of fused bioactive heterocyclic backbones containing quinoline, pyrrolidone, and β-lactam with high bond-forming efficiency.

Abstract
AbstractLactams are very important heterocycles as a result of their presence in a wide range of bioactive molecules, natural products and drugs, and also due their utility as versatile synthetic intermediates. Due to these reasons, numerous efforts have focused on the development of effective and efficient methods for their synthesis. Compared to conventional two-component reactions, multicomponent reactions (MCRs), particularly isocyanide-based MCRs, are widely used for the synthesis of a range of small heterocycles including lactam analogues. Despite their numerous applications in almost every field of chemistry, as yet there is no dedicated review on isocyanide-based multicomponent reactions (IMCRs) concerning the synthesis of lactams. Therefore, this review presents strategies towards the synthesis of α-, β-, γ-, δ- and ε-lactams using IMCRs or IMCRs/post-transformation reactions reported in the literature between 2000 and 2020.1 Introduction2 Developments in Lactam Synthesis2.1 α-Lactams2.2 β-Lactams2.3 γ-Lactams2.3.1 General γ-Lactams2.3.2 Benzo-Fused γ-Lactams2.3.3 Spiro γ-Lactams2.3.4 α,β-Unsaturated γ-Lactams2.3.5 Polycyclic Fused γ-Lactams2.4 δ-Lactams2.5 ε-Lactams3 Conclusions

Abstract
Benzimidazoles and quinoxalinones are present in the core of many pharmacologically relevant compounds. Several combinatorial methods have been developed to attach ring systems to both scaffolds for derivatization at select positions. Herein, we describe the development of novel constrained heterocyclic compounds attached to the N1 position of both benzimidazole and quinoxalinone scaffolds. Utilizing robust post-Ugi cyclization methods, including the Ugi-deprotection-cyclization (UDC) methodology, allows for efficient access to a new area of chemical space. Additionally, molecular modeling and in cellulo screening was employed to therapeutically validate the compounds formed with this method.

Abstract
![]()
Isocyanide-based
multicomponent reactions (IMCR) are by far the
most versatile reactions that can construct relatively complex molecules
by one-pot synthesis. More importantly, the development of post IMCR
modifications significantly improves the scaffold’s diversity.
Here, we describe the use of N-Boc protected hydrazine
together with α-amino acid derived isocyanides in the Ugi tetrazole
reaction and its post cyclization under both acidic and basic conditions.
The cyclization in acidic conditions was conducted in a one pot fashion,
which give 7-aminotetrazolopyrazinone (6) and tetrazolotriazepinone
(7) cyclic products. The post cyclization under basic
condition could selectively afford Boc-protected 7-aminotetrazolopyrazinone
(8) products in yield of 38–87%.

Abstract

Pd-catalyzed
cross-coupling reactions that form C–N bonds
have become useful methods to synthesize anilines and aniline derivatives,
an important class of compounds throughout chemical research. A key
factor in the widespread adoption of these methods has been the continued
development of reliable and versatile catalysts that function under
operationally simple, user-friendly conditions. This review provides
an overview of Pd-catalyzed N-arylation reactions found in both basic
and applied chemical research from 2008 to the present. Selected examples
of C–N cross-coupling reactions between nine classes of nitrogen-based
coupling partners and (pseudo)aryl halides are described for the synthesis
of heterocycles, medicinally relevant compounds, natural products,
organic materials, and catalysts.

Abstract
Various readily available, Ugi-derived dehydroalanines were used as pivotal templates to easily and efficiently assemble diverse pharmacologically important polyheterocyclic systems through cascade palladium-catalyzed C-C bond formation processes. Allyl, homoallyl and propargylamine led to the formation of benzopyrrolizidinones, benzoindolizidinones and pyrazinoisoquinolines, respectively, while benzylamines and o-bromobenzylamines were used as precursors of tetracyclic-fused systems and pyrazionoisoquinolindiones.

Abstract
The Ugi-4CR is by far one of the most successful multicomponent reactions leading to high structural diversity and molecular complexity. However, the reaction mostly affords a linear peptide backbone, enabling post-Ugi transformations as the only solution to rigidify the Ugi-adduct into more drug like species. Not surprisingly, the development of these transformations, leading to new structural frameworks, has expanded rapidly over the last few years. As expected, palladium-catalyzed reactions have received the foremost attention, yet other metals, particularly gold complexes, are fast catching up. This tutorial review outlines the developments achieved in the past decade, highlighting the modifications that are performed in a sequential or domino fashion with emphasis on major concepts, synthetic applications of the derived products as well as mechanistic aspects.

Abstract
The tuning of selective ring closure is a nontrivial challenge in synthetic organic chemistry. Herein we report a solvent switchable metal-free [4 + 2] cycloaddition approach via Csp(2)-H functionalization. The protocol is highly atom economical with water being the only by-product, delivering N-substituted benzo[e]- or [f]isoindolones in high yields.

Abstract
Five-component sequential Ugi/nucleophilic addition reaction of aromatic aldehydes, primary amines, propiolic acid, isocyanides, and hydrazides has been developed in order to access polyfunctional pseudopeptides. The reaction may proceed through formation of N-substituted 2-alkynamides as intermediates. This process is found to be mild and operationally simple with broad substrate scope.

The aldol reaction has been evaluated in combination with the Ugi multicomponent reaction to assemble richly decorated mono- and polycyclic systems via expeditious cascade pathways. A small collection of pyrrolinones was generated thereof, and the scarcely accessible pyridoquinoxalinedione scaffold was also prepared by designing an additional nucleophilic substitution step in this domino sequence requiring minimal operational effort.
