Copper catalyzed asymmetric propargylation of aldehydes

The highly enantio- and regioselective copper catalyzed asymmetric propargylation of aldehydes with a propargyl borolane reagent is reported. The methodology demonstrated broad functional group tolerance and provided high enantioselectivities for aliphatic, vinyl, and aryl aldehydes. The utility of the TMS homopropargylic alcohols was demonstrated by the facile conversion to a chiral dihydropyranone.

Asymmetric synthesis and bioselective activities of alpha-amino-phosphonates based on the dufulin motif

The asymmetric synthesis of enantiomerically pure alpha-aminophosphonates with high and bioselective activities is a challenge. Here, we report that both enantiomers of alpha-aminophosphonates bearing the N-benzothiazole moiety can be prepared in high yields (up to 99%) and excellent enantioselectivities (up to 99% ee) by using chiral thiourea organocatalysts. Evaluation of the antiviral activities of our reaction products against cucumber mosaic virus (CMV) led to promising hits with high and selective biological activities, wherein (R)-enantiomers exhibit higher biological activities than the corresponding (S)-enantiomers. Especially, compound (R)-3b with excellent anti-CMV activity (curative activity, 72.3%; protection activity, 56.9%; and inactivation activity, 96.9%) at 500 mug/mL emerged as a potential inhibitor of the plant virus. The difference in the selective bioactivity could be affected by the combination mode of the three-dimensional space between the enantiomers of alpha-aminophosphonate and cucumber mosaic virus coat protein (CMV-CP) via florescence spectroscopy and molecular docking.

Copper-Catalyzed Tandem Hydrocupration and Diastereo- and Enantioselective Borylalkyl Addition to Aldehydes

We report the copper-catalyzed stereoselective addition of in situ generated chiral boron-alpha-alkyl intermediates to various aldehydes including alpha,beta-unsaturated aldehydes under mild conditions. This tandem and multicomponent method facilitated the synthesis of enantiomerically enriched 1,2-hydroxyboronates bearing contiguous stereocenters in good yield with high diastereo- and enantioselectivity up to a ratio greater than 98:2. In particular, alpha,beta-unsaturated aldehydes were successfully used as electrophiles in Cu?H catalysis through 1,2-addition without significant reduction. The resulting 1,2-hydroxyboronates were used in various transformations.

Design, synthesis and biological evaluation of new embelin derivatives as CK2 inhibitors

A new series of furan embelin derivatives was synthesized and characterized as ATP-competitive CK2 inhibitors. The new compounds were efficiently synthesized using a multicomponent approach from embelin (1), aldehydes and isonitriles through a Knoevenagel condensation/Michael addition/heterocyclization. Several compounds with inhibitory activities in the low micromolar or even submicromolar were identified. The most active derivative was compound 4l (2-(tert-butylamino)-3-(furan-3-yl)-5-hydroxy-6-undecylbenzofuran-4,7-dione) with an IC50 value of 0.63 muM. It turned out to be an ATP competitive CK2 inhibitor with a Ki value determined to be 0.48 muM. Docking studies allowed the identification of key ligand-CK2 interactions, which could help to further optimize this family of compounds as CK2 inhibitors.

Radical Cation Cyclopropanations via Chromium Photooxidative Catalysis

The chromium photocatalyzed cyclopropanation of diazo reagents with electron-rich alkenes is described. The transformation occurs under mild conditions and features specific distinctions from traditional diazo-based cyclopropanations (e.g., avoiding beta-hydride elimination, chemoselectivity considerations, etc.). The reaction appears to work most effectively using chromium catalysis, and a number of decorated cyclopropanes can be accessed in generally good yields.
