Homochiral beta-sulfinyl nitrones can be prepared from secondary amines in three steps. Enantioselective synthesis of defensive alkaloid (+)- euphococcinine (9) has been accomplished by means of diastereoselective allylation of homochiral beta-sulfinyl nitrone (13) followed by intramolecular 1,3-dipolar cycloaddition reaction.

Herein, we describe a protocol for alkylation reactions of C(sp3)-H bonds with diacyl peroxides by means of a process involving cross-coupling between an alkyl radical and an alpha-Aminoalkyl radical. The mild, catalyst-And additive-free conditions make this protocol superior to previously reported C(sp3)-H alkylation strategies. The protocol was applied to 1,2,3,4-Tetrahydroisoquinolines and a tetrahydro-beta-carboline derivative and could be carried out on a gram scale, indicating its utility for the alkylation of late-stage synthetic intermediates.

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.

A solvent-free synthesis of alpha-aminonitriles and beta-nitroamines by oxidative cross-dehydrogenative coupling under aerobic condition is reported. A catalytic amount of molybdenum(vi) acetylacetonoate was found to catalyze cyanation of tertiary amines to form alpha-aminonitriles, whereas vanadium pentoxide was found to promote aza-Henry reaction to furnish beta-nitroamines. Both of these environmentally benign reactions are performed in the absence of solvents using molecular oxygen as an oxidant.

Further structure-activity relationship (SAR) studies with the 1,2,3,4-tetrahydroisoquinoline (THIQ) class of 5-HT1A ligands led to the synthesis of new 1-adamantoyloaminoalkyl derivatives. The impact of substituent variations in the aromatic part of THIQ moiety on 5-HT1A and 5-HT2A receptor affinities, as well as in vivo functional properties of the investigated compounds were discussed. It was found that modification reduced the binding affinity for 5-HT1A receptors (in comparison with unsubstituted THIQ derivatives); however, the majority of new compounds still remained potent 5-HT1A ligands (Ki = 4.9-46 nM) and most of them showed features of partial agonists of postsynaptic 5-HT1A receptors. At the same time, their 5-HT2A receptor affinity was slightly increased (Ki = 40-1475 nM), which resulted in a loss of 5-HT2A/5-HT1A selectivity. 5-Br,8-OCH3 derivative – the most potent, mixed 5-HT1A/5-HT2A ligand – produced activation of presynaptic 5-HT1A receptors and showed properties of a 5-HT2A receptor antagonist.

Epilepsy is a common neurological disorder caused by an imbalance between inhibitory and excitatory neurotransmission. It is well known that neuronal excitability is related to gamma-aminobutyric acid (GABA)ergic depolarization. HCO3?-dependent depolarization can be suppressed by membrane-permeable inhibitors of carbonic anhydrase. We previously identified some isoquinoline sulfonamides as potent and selective inhibitors of the human carbonic anhydrase II and VII (hCA II and hCA VII) isoforms. Given that hCA II and hCA VII are specific isoforms involved in GABA-mediated neuronal excitation, we hypothesized that they could represent the biological target for the development of new anticonvulsant agents. Therefore, for selected isoquinoline sulfonamides, we preliminarily tested their ability to prevent audiogenic seizures in DBA/2 mice. All compounds were evaluated after intraperitoneal administration, and some of them proved to protect the mice against convulsions. Among this series of compounds, several derivatives showed combined in vivo efficacy with inhibitory effects toward the targeted carbonic anhydrases (i.e., hCA II and hCA VII). Specifically, the most interesting molecule was 1-(4-aminophenyl)-6,7-dimethoxy-3,4-dihydroisoquinoline-2(1H)-sulfonamide (6), which proved to be a more active and selective hCA VII inhibitor than the reference compound topiramate. Further studies to explore the in vivo pharmacokinetic profile of the most active compounds may help to provide insight into the future design of selective hCA VII inhibitors.

(S,R)-N-PINAP was identified to be the chiral ligand for highly enantioselective CuI-catalyzed reaction of tetrahydroisoquinolines (THIQs), alkynes, and 2-bromobenzaldehyde derivatives. This enables us to accomplish the first asymmetric total synthesis of 12 natural 13-methyltetrahydroprotoberberine (13-MeTHPB) alkaloids in only three catalytic steps with 47-64% overall yields. In addition, the Pd-catalyzed reductive Heck cyclization was successfully extended to three Pd-catalyzed domino reactions (Heck/Suzuki, Heck/Sonogashira, and Heck/Heck), which greatly expands the synthetic utility of this catalytic strategy and allows expeditious access to 13-substituted tetrahydroprotoberberines for further bioactivity evaluation.
