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.

3,7-Diazabicyclo[3.3.1]nonane (bispidine) based nicotinic acetylcholine receptor (nAChR) ligands have been synthesized and evaluated for nAChRs interaction. Diverse spacer motifs were incorporated between the hydrogen bond acceptor (HBA) part and a variety of substituted (hetero)aryl moieties. Bispidine carboxamides bearing spacer motifs often showed high affinity in the low nanomolar range and selectivity for the alpha4beta2* nAChR. Compounds 15, 25, and 47 with Ki values of about 1 nM displayed the highest affinities for alpha4beta2* nAChR. All evaluated compounds are partial agonists or antagonists at alpha4beta2*, with reduced or no effects on alpha3beta4* with the exception of compound 15 (agonist), and reduced or no effect at alpha7 and muscle subtypes.

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.

Recent work in our laboratory has shown that the highly substituted, electronically rich 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid (THIQ3CA) scaffold is a key building block for a novel class of promising anticoagulants.10 The synthesis of THIQ3CA analogs, especially containing specific, electronically rich substituents, has been a challenge and essentially no efficient methods have been reported in the literature. We describe three complementary, glycine donor-based strategies for high yielding synthesis of highly substituted, electronically rich THIQ3CA esters. Three glycine donors studied herein include hydantoin 1, (±)-Boc-alpha- phosphonoglycine trimethyl ester 2, and (±)-Z-alpha-phosphonoglycine trimethyl ester 3. Although the synthesis of THIQ3CA analogs could be achieved using either of the three, an optimal, high yielding approach for the desired THIQ3CA esters was best achieved using 3 in three mild, efficient steps. Using this approach, a focused library of advanced N-arylacyl, N-arylalkyl, and bis-THIQ3CA analogs was synthesized. Variable temperature and solvent-dependent NMR chemical shift studies indicated the presence of two major conformational rotamers in 3:1 proportion for N-arylacyl-THIQ3CA analogs, which were separated by a high kinetic barrier of ?17 kcal/mol. In contrast, N-arylalkyl and bis-THIQ3CA variants displayed no rotamerism, which implicates restricted rotation around the amide bond as the origin for high-barrier conformational interconversion. This phenomenon is of major significance because structure-based drug design typically utilizes only one conformation. Overall, the work presents fundamental studies on the synthesis and conformational properties of highly substituted, electronically rich THIQ3CA analogs.
