Abstract
A 1,1'-bi-2-naphthol (BINOL)-derived disulfonimide (DSI)-catalyzed enantioselective aza-Friedel-Crafts reaction between 1,3,5-trialkoxy benzenes and N-sulfonyl aldimines gives direct access to a series of chiral diarylmethylamines in good yields and good to excellent enantioselectivities (up to 97% ee). This reaction provides a useful protocol for the direct synthesis of diarylmethylamine derivatives.

Abstract
The first stereoselective propargylic dearomatization of 2-naphthol derivatives is reported using a chiral CuII-L10 complex. The reaction shows chemodivergent reactivity and produced propargyl dearomatization and etherification product for differently substituted 2-naphthols. Both the reactions generate the desired products in high yields with excellent chemo- and stereoselectivities (up to 99% ee, dr = 9:1) by using only 2 mol % catalyst loading. Dearomatization products contain a contiguous all-carbon quaternary-tertiary stereocenter and a terminal alkyne functionality.

Abstract
Naphthols, hydroxyindoles and an activated phenol are reacted with differently substituted (E)-nitrobut-1-en-3-ynes using the commercially available Rawal's chiral squaramide. The corresponding β-nitroalkynes were obtained with good yields and excellent enantioselectivities. Moreover, dihydronaphthofurans can be accessed via silver catalysed cyclization in a tandem one-pot procedure, with high preservation of the optical purity.

Abstract
By merging organocatalysis with copper catalysis, a highly efficient stereospecific approach for the synthesis of chiral phenols from cyclohexanones has been developed for the first time. The aromatization reaction proceeds through the in situ formation of enone intermediates and further subsequent bromination/dehydrobromination reactions. And a series of functionalized phenol derivatives are obtained in good yields (up to 89%) and good to excellent enantioselectivities (up to 99% ee).

Abstract
Naphthols and 3-trifluoroethylidene oxindoles were found to undergo an asymmetric Friedel-Crafts alkylation/lactonization reaction, catalyzed by only 2.5 mol % of a quinine-derived squaramide catalyst, to afford the corresponding α-aryl-β-trifluoromethyl dihydrocoumarin derivatives in high yields (up to 99 %) with excellent enantio- and diastereoselectivities (up to 98 % ee, >20:1 d.r.). Importantly, the lactonization proceeded by nucleophilic attack of the naphthol hydroxy group at the amide motif of the oxindoles under mild reaction conditions. This protocol represents a new strategy for the formation of dihydrocoumarins by an efficient intramolecular amide C-N bond-cleavage and esterification process.
