An expedient synthesis of enantioenriched substituted (2-benzofuryl)arylcarbinols via tandem Rap–Stoermer and asymmetric transfer hydrogenation reactions
An expedientsynthesis of enantioenriched substituted (benzofuran-yl)-aryl and heteroaryl carbinols, is described. A key feature of this protocol is synthesis of functionally varied benzofuran scaffolds via a Rap–Stoermer reaction/catalytic asymmetric transfer hydrogenation (ATH) using substituted salicylaldehyde and α-haloaryl, heteroaryl ketones.

as a chiral AIE‐active material. Here, in our effort to designchiralluminogens, we have developed a design strategy in which 2‐substituted furans, when appropriately fused with the BINOL scaffold, will generate solid‐state emissive materials with high thermal and photostability as well as colour‐tunable properties. The excellent biocompatibility, together with the high fluorescence quantum yield and

Substitution of a bromo atom on either naphthalene or both naphthalene and gamma-phenyl moiety of the lactone enhanced potency while retaining the same cytotoxicity profile. The tricyclic naphtho[2,1-b]furanderivatives, prepared from 2-hydroxy-1-naphthaldehyde in an efficient pathway, also possess the same cytotoxicity profile.
