Abstract
A tricoordinate borenium ion has received considerable attention in recent years for its applications in Lewis acid catalysis. Over the years, asymmetric catalysis mediated by a chiral borenium ion has also been developed. To stabilize the electron-deficient boron atom, a series of chloroborane masked borenium ions featuring the symmetrical [B-Cl-B]+ linkage are prepared and utilized as the catalyst for the enantioselective Diels-Alder cycloaddition of cyclopentadiene and 2,2,2-trifluoroethyl acrylate. The presence of a Cp* ligand is critical in realizing the cyclic diboron compounds, and the stability of the resulting [B-Cl-B]+ cation is dependent on the steric bulkiness of the oxazolidinone moiety. The stereoselectivity of the Diels-Alder cycloaddition is controlled by the substituents of the chiral oxazolidinone ligand and could be further improved via the coordination of SnCl4 at the bridging chloride of the [B-Cl-B]+ cation.

Abstract
A Michael addition initiated cyclopropanation/[1,5]-hydrogen shift has been developed for the enantioselective synthesis of Rauhut-Currier products. The reaction of α-alkyl diazoesters and in situ generated o-quinone methides proceeds in the presence of chiral oxazaborolidinium ion, providing Z-stereocontrolled Rauhut-Currier products in high yields (up to 96%) with excellent Z/E selectivities (>20:1) and enantioselectivities (up to >99% ee). The synthetic utility was illustrated by conversion of the product to 3,4-dihydrocoumarins with two adjacent chiral stereocenters.

Abstract
Chiral oxazaborolidinium ion (COBI)-catalyzed enantioselective nucleophilic addition reactions of aldimines using tributyltin cyanide and allyltributylstannane have been developed. Various α-aminonitriles and homoallylic amines were synthesized in high yield (up to 98%) with high to excellent enantioselectivity (up to 99% ee). A rational mechanistic model for the complex of COBI and aldimine is provided to account for these enantioselective reactions.

Abstract
Boron Lewis acid catalysis has a long history and has become one of the most powerful methods for organic synthesis. In addition to achiral boron catalysts such as BX3 (X = F, Cl, Br) and B(C6F5)3, chiral boron catalysts are also significant synthetic tools used by organic chemists in academic laboratories and industry. Since first reported by Corey et al. in 2002 ( Corey et al. J. Am. Chem. Soc. 2002 , 124 , 3808 ), the chiral oxazaborolidinium ion (COBI), an activated form of proline-derived oxazaborolidine, has been used as a strong Lewis acid catalyst. Although the early examples of asymmetric synthesis through COBI-catalyzed nucleophilic 1,2- or 1,4-carbonyl additions were reported in 2004-2006, Diels-Alder and cycloaddition reactions of various carbonyl compounds were mostly developed over the next several years to afford enantioenriched cyclized products. The power of COBI in catalyzing carbonyl 1,2- or 1,4-addition reactions triggered our interest in developing asymmetric synthetic methodologies to generate versatile enantiomerically enriched compounds. In this Account, we summarize our recent studies on COBI-catalyzed asymmetric nucleophilic carbonyl addition and tandem reactions. Logical mechanistic explanations of asymmetric COBI catalysis are also discussed. The proton-activated COBI catalyst, which can activate various carbonyl compounds such as aldehydes, ketones, acroleins, and enones through Lewis acid-base interactions and synergistic hydrogen bonds, facilitates asymmetric 1,2- or 1,4-carbonyl additions of nucleophiles. Nucleophiles bearing trialkylsilyl groups successfully reacted with aromatic, aliphatic, and α,β-unsaturated aldehydes through 1,2-addition reactions resulting in chiral β-hydroxy esters. In addition, efficient asymmetric hydrosilylation of ketones was achieved with a TfOH-activated COBI catalyst. Optically active β-keto esters and all-carbon quaternary aldehydes were synthesized successfully through asymmetric 1,2-addition of diazo compounds and tandem H- or C-migration, respectively. In some cases, epoxide products were obtained as side products via the Darzens reaction pathway. Solvent and π-π interactions played important roles in favoring C-migration over H-migration. Nucleophilic 1,4-addition of diazo compounds and chemoselective ring-closure afforded an efficient approach to cyclopropanes, and their tandem rearrangements provided four- and seven-membered cyclic compounds with excellent stereoselectivity. After a Michael addition of diazo compounds, the selective β-hydride shift pathway afforded the β-substituted cyclic enones with high diastereo- and enantioselectivity. The presence of π-bond(s) in the substituents at the α-position of the diazo compound hindered the β-hydride shift pathway and, as a result, favored the cyclopropanation pathway. While there still remain challenges to be overcome, these results further understanding of COBI catalysis and open a window for future development of new asymmetric synthetic methods using carbonyl addition and tandem reactions.

Abstract
Chiral Lewis acid catalyzed asymmetric formation of cyclobutanones from α-silyloxyacroleins and α-alkyl or α-aryl diazoesters has been developed. In the presence of a chiral oxazaborolidinium ion catalyst, various α-silyloxycyclobutanones possessing a chiral β-quaternary center were synthesized in high yield (up to 91%) with excellent enantio- and diastereoselectivity (up to 98% ee and up to >20:1 dr) through tandem cyclopropanation/semipinacol rearrangement. The synthetic potential of this method was illustrated by conversion of the product to various cyclic compounds such as γ-lactone, cyclobutanol, and cyclopentanone.

Abstract
A study of the reactivity and diastereoselectivity of the Lewis acid promoted cascade cyclizations of both acyclic and macrocyclic alkynones is described. In these reactions, a β-iodoallenolate intermediate is generated via conjugate addition of iodide to an alkynone followed by an intramolecular aldol reaction with a tethered aldehyde to afford a cyclohexenyl alcohol. The Lewis acid magnesium iodide (MgI2) was found to promote irreversible ring closure, while cyclizations using BF3·OEt2 as promoter occurred reversibly. For both acyclic and macrocyclic alkynones, high diastereoselectivity was observed in the intramolecular aldol reaction. The MgI2 protocol for cyclization was applied to the synthesis of advanced intermediates relevant to the synthesis of phomactin natural products, during which a novel transannular cation-olefin cyclization was observed. DFT calculations were conducted to analyze the mechanism of this unusual MgI2-promoted process.

Abstract
A formal synthesis of merrilactone A has been completed using a domino 1,4-addition-aldol process as the key step. Both iodo- and cyano-1,4-addition-aldol cyclizations were productive in forming the highly hindered C1-C9 bond linking vic-quaternary and tertiary stereocenters. The latter method was used to complete a formal total synthesis of the natural product.

Abstract
We report a highly enantioselective Morita-Baylis-Hillman (MBH) reaction of isatins and acrolein to provide enantiomerically enriched 3-substituted 3-hydroxyoxindoles, which could serve as valuable synthetic building blocks. This is also the first time that a ketone has been used as the electrophile and acrolein as the nucleophile in a highly enantioselective catalytic asymmetric MBH reaction. Hatakeyama's catalyst, β-isocupreidine (1), turned out to be a powerful catalyst for this transformation.
