An organocatalytic [4 + 1] cyclization of o-QMs with MBH carbonates has been established using naphthylindole-derived phosphine (NIP) as an organocatalyst. By using this approach, a series of 2,3-dihydrobenzofuran derivatives have been synthesized in high yields and excellent diastereoselectivities (up to 99% yield, >95:5 dr). This reaction not only has established the first [4 + 1] cyclization of o-QMs with MBH carbonates but also represents the first application of naphthylindole-derived phosphines as organocatalysts in catalytic reactions. In addition, this reaction has also provided a useful method for constructing 2,3-dihydrobenzofuran scaffolds.

Chiral phosphoric acids (HB*) catalyze the asymmetric desymmetrization of meso 1,3-diols through mono-transacetalization with a tethered acetal unit (see scheme). This new strategy leads to the efficient assembly of tetrahydrofuran and tetrahydropyran skeletons bearing remote all-carbon-substituted quaternary stereocenters that are not straightforward to access by other methods.

A cascade reaction of N-aryl-alpha,beta-unsaturated nitrones and electron-deficient allenes has been discovered that allows single-step access to 3-functionalized indoles that usually require preformation and alkylation of an indole precursor. The heterocycles prepared through the hydrogen bond donor catalyzed cascade reaction are poised to undergo a McMurry coupling to form previously synthetically elusive cycloheptanone-fused indoles. The scope of these transformations is discussed as well as mechanistic experiments describing proposed intermediates of the cascade reaction and an initial catalytic asymmetric example that generates a carbon stereocenter during the cascade process.

An efficient and transition-metal-free approach was developed to access a series of fluorinated heteroaromatics in moderate to excellent yields. This one-pot procedure features a triple-relay transformation of rapid dearomatization, fluorination, and rearomatization processes, which represents a conceptually novel strategy of combining partial hydrogenation and electrophilic fluorination.

Optically pure 2-(quinolin-8-yloxy)cyclohexan-1-ol 1, obtained via simple chemical and bio-catalytic steps, was used as a chiral solvating agent for molecular recognition of the enantiomers of acids. The discrimination of isomers was detected by NMR or fluorescence spectroscopy. Isomers of alpha-substituted carboxylic acids, phosphoric acids, unprotected amino acids and dipeptides were efficiently detected, while the method can be used for quantitative determination for practical applications. Analysis of the crystal of (R,R)-1 (R)-mandelic acid established a three point supramolecular interaction.

A Br°nsted acid/Lewis acid dual catalyst system was developed to promote efficient C-C bond formation between a range of oxocarbenium precursors derived from chromene acetals and ethyl diazoacetate. The reaction proceeds under mild conditions and is tolerant of functionalized 2H-chromenes and isochromene acetals. In addition, an asymmetric variant of diazoacetate addition towards 2H-chromene acetals is described. Continued investigations include further optimization of asymmetric induction towards the formation of diazo ester substituted 2H-chromene.
