WO3 nanospheres with improved catalytic activity for visible light induced cross dehydrogenative coupling reactions

Three tungsten oxides (WO3-W1 to WO3-W3) with different morphologies were prepared and characterized by XRD, SEM, TEM and HR-TEM measurements. The as-synthesized tungsten oxides were screened as photocatalysts for visible-light-driven cross dehydrogenative coupling (CDC) reactions along with commercially available WO3-W4. Preliminary studies showed that WO3-W1 with hollow sphere morphology efficiently photocatalyzed oxidative C?H functionalization as compared to other tested samples, by using molecular oxygen as a benign oxidant. The superior photocatalytic performance of WO3-W1 can be attributed to its larger surface area and pore structure which was supported by nitrogen adsorption-desorption measurements. Further, this protocol was used to synthesize alpha-functionalized tertiary amines in good to excellent yields by irradiating a mixture of WO3-W1, tertiary amine, and nucleophiles (nitromethane or ketones) to visible light under aerobic conditions. Moreover, WO3-W1 can be recycled and reused with no obvious change in catalytic activity, indicating that this is an environmentally friendly and economical protocol and also underlines the robustness of the catalysts in light mediated cross dehydrogenative coupling reactions. It is hoped that our results could offer useful information for designing of new heterogeneous semiconductors for photoredox catalytic organic reactions.

Oxidative alpha-Trichloromethylation of Tertiary Amines: An Entry to alpha-Amino Acid Esters

alpha-Trichloromethylation of tertiary amines with trimethyl(trichloromethyl)silane by oxidative coupling, using DDQ as an oxidant, has been realized. The reaction is instantaneous, is scalable, and tolerates a broad range of functional groups and heteroarenes. The trichloromethylated products can be easily converted into beta,beta-dichloroamines, enamines, and alpha-amino acid esters under operationally simple conditions. This methodology provides an efficient alternative to the poisonous cyanation reactions for the synthesis of carboxylic acid and their derivatives.

An Enantioselective Access to 1-Alkyl-1,2-Dihydroisoquinolines and 1-Alkyl-, 3-Alkyl-, and 1,3-Dialkyl-1,2,3,4-tetrahydroisoquinolines

New chiral isoquinolinium salt derivatives 1, 2 or 3 have been treated with Grignard reagents to give as major products, 1-substituted 1,2-dihydroisoquinolines 4a-f, oxazolidine derivatives 10a-f or 21, respectively, in good yield and in moderate to good diastereoisomeric excess. The stereochemistry of these new derivatives has been elucidated, in particular, by X-ray crystallographic studies of 1,2-dihydroisoquinoline 4b and the minor oxazolidine lib. Reduction of all these intermediates gave chiral 1-substituted 1,2,3,4-tetrahydroisoquinolines such as base 8. The enantioselective synthesis of the natural alkaloid (-)-salsonidine in three steps and 38% overall yield from salt 3 is described as an application. Reduction of salt 2 gave a new oxazolidine derivative 15 which is a practical intermediate for the synthesis of 3-alkyl 1,2,3,4-tetrahydroisoquinolines 17a,b, while oxazolidines such as 10 are convenient precursors of 1,3-disubstituted tetrahydroisoquinolines, as illustrated by a synthesis of 1,3-dimethyl tetrahydroisoquinoline 20.

Chemical modifications of the N-methyl-laudanosine scaffold point to new directions for SK channels exploration

An asparagine or a histidine are present in a similar position in the outer pore region of SK2 and SK3 channels, respectively. Therefore, this structural difference was targeted in order to develop selective blockers of SK channel subtypes. Following docking investigations, based on theoretical models of truncated SK2 and SK3 channels, the benzyl side chain of N-methyl-laudanosine (NML) was functionalized in order to target this specific amino-acid residues. Chiral butanamide and benzyloxy analogues were prepared, resolved and tested for their affinity for SK2 and SK3 channels. Isoquinolinium (NMIQ) derivatives have a higher affinity for both SK channel subtypes than the corresponding derivative with no functionalized side chain. This trend was observed also for the 1,2,3,4-tetrahydroisoquinoline (THIQ) analogues. A benzyloxy functionalized NML enantiomer has a higher affinity than NML stereoisomers. Otherwise, the conserved affinity of these analogues led to the opportunity to further investigate in terms of possible labeling for in vivo investigations of the role of SK channels.

NHC-catalyzed Redox-Neutral Aza-Benzoin Reaction of Aldehydes with Tetrahydroisoquinolines

Tetrahydroisoquinoline derivatives are useful synthetic intermediates, which play an important role in the preparation of natural products, pharmaceuticals and other materials. Herein, we report an unprecedented redox-neutral aza-benzoin protocol to construct such scaffold. Upon exposure of tetrahydroisoquinolines to aromatic aldehydes in the presence of an NHC catalyst, the C-1 acylated tetrahydroisoquinolines were obtained in moderate to good yields.

Synthesis of 3-aryl-3-benzazepines: Via aryne [1,2] Stevens rearrangement of 1,2,3,4-tetrahydroisoquinolines

An efficient method for the synthesis of 3-aryl-3-benzazepines via aryne induced [1,2] Stevens rearrangement of 1,2,3,4-tetrahydroisoquinolines is described. This approach provided straightforward access to 3-aryl-3-benzazepines in moderate to good yields under transition-metal-free and strong-base-free conditions. Temperature-dependent alpha-arylated products of the carbonyl group were also obtained. Preliminary mechanistic studies suggest both 3-aryl-3-benzazepines and alpha-arylated products of the carbonyl group were generated via the rearrangement of nitrogen ylide intermediates.
