The first palladium-catalyzed diastereoselective conjugate addition of arylboronic acids to chiral imides is reported. The catalytic system employing 4-tert-butyloxazolidin-2-one as the chiral auxiliary in a mixed solvent system of MeOH/H2O (1:3) under an air atmosphere provides the optically active 3-arylbutanoic acid derivatives in excellent yields with high diastereoselectivity.

Abstract

The first one-step method for the synthesis of ortho-N-heteroaromatic trifluoromethoxy derivatives by site-specific O−CF3 bond formation using hydroxylated N-heterocycles and Togni's reagent is described. The approach enables the unprecedented syntheses of a wide range of six or five-membered N-heteroaromatic trifluoromethoxy compounds containing one or two heteroatoms from most commonly used hydroxylated N-heterocycles. Notable advantages of this method include its simplicity and mild conditions, avoidance of the need for metals or toxic reagents, and compatibility with a variety of functional groups. Furthermore, this method is especially suitable for the larger scale application.

Abstract

A novel selective fluorescence probe that contains 2-p-phenylimidazo[4,5-f][1,10]phenanthroline and a viologen unit linked by a flexible chain was synthesized and found to be able to select zinc ions with a clear fluorescence enhancement and a large stokes shift in aqueous solution. This probe can also be designed as an onoffon molecular switch by the formation and rupture of a supramolecular nanocapsule with cucurbit[8]uril (CB[8]) in aqueous solution.

The supramolecular self-assembly in aqueous solution of N-alkyl-N′-methyl-4,4′-bipyridinium ([CmMV]2+) (m = 4, 5, 7, 12), 1,4-dihydroxybenzene (HB), and 2,6-dihydroxynaphthalene (HN) with cucurbit[8]uril (CB[8]) was investigated with 1H NMR, NOESY, ESI-MS, and UV–vis spectroscopy. It has been reported that these three compounds ([CmMV]2+ (m = 12), HN and CB[8]) can form 1:1:1 inclusion complex with the C12 alkyl chain of [C12MV]2+ being present outside the cavity. Here we report that [CmMV]2+ (m ⩾5), HB, and CB[8] can form a new supramolecular self-assembly binding mode with the alkyl chain being present inside the cavity.

A two-step process for the synthesis of aryl and heteroaryl trifluoromethyl ketones from the corresponding aldehydes is described. Trifluoromethyl alcohols were prepared from aryl and heteroaryl aldehydes in excellent yields using catalytic amount of K2CO3.
