Abstract
The rational combination of two catalysts to expedite the construction of chiral complex biologically and pharmacologically relevant chiral compounds has widely gained momentum over the past decade. In particular, enamine or iminium catalysis ensuing from the activation of aldehyde or ketone by chiral amine catalysts in conjugation with other organocatalytic cycles has facilitated several asymmetric transformations to yield the enantioenriched products. Regardless of the considerable discussion on the various dual catalytic approaches, literature lacks a comprehensive review focusing on the enamine and iminium-based dual organocatalytic systems. Thus, this review article has discussed the noteworthy achievements in the field of asymmetric catalysis and synthesis catalyzed by the enamine and iminium-based dual organocatalytic systems.

Abstract
A highly diastereoselective method for the synthesis of syn-β-amino alcohols and enantioenriched anti-β-amino alcohols has been developed involving α-hydroxyl aldehydes and chiral α-phenylaminoxyaldehydes or α-benzoyloxyaldehydes, respectively in Petasis borono-Mannich allylation reactions. This study broadens the scope and utility of the Petasis reaction to include pinacol allylboronate and highlights its unique reactivity and stereochemical outcomes.

Abstract
![]()
Herein, we report the stereoselective
and convergent synthesis
of resolvin E4, a newly identified specialized pro-resolving mediator.
This synthesis proves the absolute configuration and exact olefin
geometry. Key elements of the successful strategy include a highly
stereoselective MacMillan organocatalytic oxyamination, a Midland
Alpine borane reduction, and the use of a 1,4-pentadiyne unit as a
linchpin building block. The application of reaction telescoping in
several of the synthetic transformations enabled the preparation of
the resolvin E4 methyl ester in 10% yield over 10 steps (longest linear
sequence). The physical property (UV–Vis and LC–MS/MS)
data of synthetic resolvin E4 matched those obtained from biologically
produced material.

Abstract
An enantioselective total synthesis of latanoprost was achieved. Its chiral cyclopentane core structure was constructed through an organocatalyst-mediated [3+2]-cycloaddition reaction, and chirality in the ω-side chain was generated by prolinate-anion-mediated α-aminoxylation of an aldehyde. Highly diastereoselective domino acetalization and an oxy-Michael reaction were key steps for the generation of C9 chirality.

Abstract
The highly enantioselective totally N-selective hydroxyamination reaction of α-aryl-α-cyanoacetates with 2-nitrosopyridines was realized by using a chiral N,N'-dioxide/Mg(OTf)2 complex as catalyst, which enriches the nitroso chemistry. A variety of 2-cyano-2-[hydroxyl(pyrydin-2-yl)amino]acetates with quaternary stereocenters and potential antibacterial activities were obtained in excellent yields with good to excellent ee values under as low as 0.05 mol % catalyst loading. The products could be easily transformed to useful α-amino amides and 1,2-diamines. Besides, a possible transition state model was proposed to elucidate the origin of the chirality induction.
