Abstract
A highly enantioselective Mannich reaction of α-fluoroindanones with isatin-derived N-Boc-ketimines catalyzed by a quinine-derived phase-transfer catalyst was developed. A variety of 3-substituted 3-amino-2-oxindoles bearing fluorine-containing, vicinal, tetrasubstituted stereocenters were constructed using this protocol in high yields (83-95%), with moderate to excellent enantioselectivities (66-91%) and high diastereoselectivities (up to >99:1).

Abstract
AbstractThis review is devoted to underpinning the contributions of Indian researchers towards asymmetric organocatalysis. More specifically, a comprehensive compilation of reactions mediated by a wide range of non-covalent catalysis is illustrated. A detailed overview of vividly catalogued asymmetric organic transformations promoted by hydrogen bonding and Brønsted acid catalysis, alongside an assortment of catalysts is provided. Although asymmetric organocatalysis has etched itself in history, we aim to showcase the scientific metamorphosis of Indian research from baby steps to large strides within this field. 1 Introduction2 Non-Covalent Catalysis and Its Various Activation Modes3 Hydrogen-Bonding Catalysis3.1 Urea- and Thiourea-Derived Organocatalysts3.1.1 Thiourea-Derived Organocatalysts3.1.2 Urea-Derived Organocatalysts3.2 Squaramide-Derived Organocatalysts3.2.1 Michael Reactions3.2.2 C-Alkylation Reactions3.2.3 Mannich Reactions3.2.4 [3+2] Cycloaddition Reactions3.3 Cinchona-Alkaloid-Derived Organocatalysts3.3.1 Michael Reactions3.3.2 Aldol Reactions3.3.3 Friedel–Crafts Reactions3.3.4 Vinylogous Alkylation of 4-Methylcoumarins3.3.5 C-Sulfenylation Reactions3.3.6 Peroxyhemiacetalisation of Isochromans3.3.7 Diels–Alder Reactions3.3.8 Cycloaddition Reactions3.3.9 Morita–Baylis–Hilman Reactions4 Brønsted Acid Derived Organocatalysts4.1 Chiral Phosphoric Acid Catalysis4.1.1 Diels–Alder Reactions4.1.2 Addition of Ketimines4.1.3 Annulation of Acyclic Enecarbamates5 Conclusion

Abstract
A series of tetraamino-bisthiourea chiral macrocycles containing two diarylthiourea and two chiral diamine units were synthesized by a fragment-coupling approach in high yields. Different chiral diamine units, including cyclohexanediamines and diphenylethanediamines were readily incorporated by both homo and hetero [1 + 1] macrocyclic condensation of bisamine and bisisothiocyanate fragments. With the easy synthesis, gram-scale of macrocycle products can be readily obtained. These chiral macrocycles were applied in catalyzing bioinspired decarboxylative Mannich reactions. Only 5 mol % of the optimal macrocycle catalyst efficiently catalyzed the decarboxylative addition of a broad scope of malonic acid half thioesters to isatin-derived ketimines with excellent yields and good enantioselectivity. The rigid macrocyclic framework and the cooperation between the thiourea and tertiary amine sites were found to be crucial for achieving efficient activation and stereocontrol. As shown in control experiments, catalysis with the acyclic analogues having the same structural motifs were non-selective.

Abstract
The chiral keto-substituted propargylamines are an essential class of multifunctional compounds in the field of organic and pharmaceutical synthesis and have attracted considerable attention, but the related synthetic approaches remain limited. Therefore, a concise and efficient method for the enantioselective synthesis of β-keto propargylamines via chiral phosphoric acid-catalyzed asymmetric Mannich reaction between β-keto acids and C-alkynyl N-Boc N,O-acetals as easily available C-alkynyl imine precursors has been demonstrated here, affording a broad scope of β-keto N-Boc-propargylamines in high yields (up to 97%) with generally high enantioselectivities (up to 97 : 3 er).

Abstract
Decarboxylative addition reactions are well known as an effective approach to
C–C bonds formation due to the availability of starting reagents, ease of handling, and low
environmental impact. This approach clearly demonstrated its potential for the synthesis
of the variety of acyclic and heterocyclic compounds, including optically active ones. The
significant amount of articles devoted to this topic published in recent years proves the
importance of this approach in modern organic synthesis. In this review, the recent
achievements in decarboxylative addition to C=C, C=N, and C=O bonds have been summarized
and discussed over the last 6 years.

Abstract
Herein we describe an organocatalytic protocol for the asymmetric synthesis of β,β-diaryl ketones. Under the catalysis of a chiral phosphoric acid, 4-hydroxybenzyl alcohols underwent dehydration to form para-quinone methides, which reacted with β-keto acids in 1,6-addition reactions. Upon treatment with Et3N in one-pot, decarboxylation proceeded to provide the desired chiral ketones in nearly quantitative yields with high enantioselectivities.

Abstract
The first organocatalytic asymmetric Mannich reaction employing 3,4-dihydro-2-quinolones has been developed for the synthesis of biologically important 3,3-disubstituted-dihydro-2-quinolones. N-Boc imine precursor amidosulfones as well as pre-formed N-Boc imine were used for this purpose. Cyclohexyldiamine derived bifunctional amino-thiourea catalysts were employed to provide the products in high enantio- and good diastereoselectivities.

Abstract
This work describes the development of a new single-pot copper(II)-catalyzed decarboxylative Michael reaction between β-keto acids and enones, followed by in situ aldolization, which results in highly functionalized chiral and achiral cyclohexenones. The achiral version of this Robinson annulation features a hitherto unprecedented Michael reaction of β-keto acids with sterically hindered β,β'-substituted enones and provides access to all carbon quaternary stereocenter-containing cyclohexenones (11 examples, 43-83% yield). In addition, an asymmetric chiral bis(oxazoline) copper(II)-catalyzed single-pot Robinson annulation has been devised for preparing chiral cyclohexenones, including some products that contain vicinal stereocenters (5 examples, 65-85% yield, 84-94% ee). This latter protocol has been successfully applied to the enantioselective formation of the oxygenated 10-nor-steroid core from readily available starting materials.
