Abstract
Organocatalytic methods have achieved spectacular advancements for the preparation of chiral molecules in highly enantioenriched forms. The fast development of this field can mainly be attributed to the evolution of general and reliable activation modes. The discovery and identification of new activation modes are therefore highly desirable to push the boundaries of asymmetric reactions. In this Minireview, recent advances in enantioselective carbonyl catalysis, one useful subbranch of organocatalysis for the efficient activation of simple amines, will be summarized. With elegantly designed chiral aldehyde catalysts, highly enantioselective and efficient asymmetric reactions can be developed. Continued development of enantioselective carbonyl catalysis is expected in the future.

Abstract
The first α-alkylation of α,β,γ,δ-unsaturated aldehydes is achieved under mild reaction conditions. Several α,β,γ,δ-unsaturated aldehydes and diarylcarbinols are successfully tested for the synthesis of MBH-type α-alkylated products with an excellent regioselectivity. Simple pyrrolidine is efficiently used as a catalyst to achieve a perfect E/Z selectivity of the α-alkylated products.

Abstract
An efficient diarylprolinol triphenylsilyl ether-catalyzed enantioselective aza-Michael reaction of pyrimidines as N-centered nucleophiles to α,β-unsaturated aldehydes, followed by reduction, provided chiral acyclic pyrimidine nucleosides in good yields (51-78% yields for two steps) and excellent enantioselectivities (91-98% ee). In addition, the chiral acyclic pyrimidine nucleoside having the tert-butyldiphenylsilyl-protected hydroxyl substituent was successfully applied to the synthesis of the corresponding chiral cyclic pyrimidine nucleoside analogue bearing the tetrahydrofuranyl ring.

Abstract
The first highly diastereo- and enantioselective synthesis of bridged O, O-acetals embedded with spirooxindoles has been developed. Dioxindoles and 2-hydroxy cinnamaldehydes were employed as the reaction partners in this method. The desired products were obtained via diaryl prolinol TBS ether catalyzed Michael reaction followed by acetal formation with TFA.

Abstract
The first catalytic approach for the asymmetric synthesis of 3,4-disubstituted cyclohexadiene carbaldehydes through an inverse-electron-demand Diels-Alder reaction is described. A variety of arylacetaldehydes and α,β,γ,δ-unsaturated aldehydes are tested under the mild reaction conditions catalyzed by l-proline to obtain the trans diastereomeric products with good yields and high enantioselectivities. The scope of this methodology is further extended to the asymmetric synthesis 3,4-disubstituted cyclohexane carbaldehydes and their derivatives. The practicality of this method is demonstrated by the gram-scale synthesis. This methodology is successfully applied for the formal total synthesis of cyclobakuchiol A, an antipyretic and anti-inflammatory agent, and cyclobakuchiol C.

Abstract
Highly diastereo and enantioselective [4+2] cycloadditions have been achieved between pyrrolidone-derived cyclic enones and α-haloaldehydes under mild conditions. Relying on extremely reactive in-situ generated chiral N-heterocyclic carbenes, this stereoselective annulation proceeds efficiently even on the gram scale with the catalyst loading as low as 0.025 mol% (250 ppm). A variety of cis-substituted bicyclic dihydropyranones can be produced in up to 96% yield with up to >99% ee. In addition, simple, inexpensive linear aldehydes such as n-propanal can be used directly in asymmetric cycloadditions via oxidative N-heterocyclic carbene organocatalysis with low catalyst loading. This method may provide an economical and practical approach for the asymmetric synthesis of medicinally relevant molecules.

Abstract
![]()
Asymmetric
and site-selective formal [3 + 2]-annulations of γ-alkyl-β,γ-unsaturated
γ-lactams with α,β-unsaturated aldehydes have been
developed. These organocatalysed transformations yield high value
enantioenriched bicyclic γ-lactams with up to four new stereocenters
(sometimes including a quarternary carbon). The overall transformation
starts from simple and readily accessible furans and oversees a rapid,
controlled, and dramatic enhancement in 3D complexity.

Abstract
![]()
The Michael addition
of nitromethane to cinnamaldehyde has been
computationally studied in the absence of a catalyst and the presence
of a biotinylated secondary amine by a combined computational and
experimental approach. The calculations were performed at the density
functional theory (DFT) level with the M06-2X hybrid functional, and
a polarizable continuum model has been employed to mimic the effect
of two different solvents: dichloromethane (DCM) and water. Contrary
to common assumption, the product-derived iminium intermediate was
absent in both of the solvents tested. Instead, hydrating the C1–C2
double bond in the enamine intermediate directly yields the tetrahedral
intermediate, which is key for forming the product and regenerating
the catalyst. Enamine hydration is concerted and found to be rate-limiting
in DCM but segregated into two non-rate-limiting steps when the solvent
is replaced with water. However, further analysis revealed that the
use of water as solvent also raises the energy barriers for other
chemical steps, particularly the critical step of C–C bond
formation between the iminium intermediate and nucleophile; this consequently
lowers both the reaction yield and enantioselectivity of this LUMO-lowering
reaction, as experimentally detected. These findings provide a logical
explanation to why water often enhances organocatalysis when used
as an additive but hampers the reaction progress when employed as
a solvent.
