The reaction of cotarnine and acyl/aryl ketones in ?green? solvents provides an efficient approach to an array of privileged 1,2,3,4-tetrahydroisoquinolines in excellent yields by metal-free activation of C(sp3)?H bonds. This one-pot procedure takes place under base-free conditions at room temperature, and tolerates a wide range of functionalities. The reaction is highly chemoselective, can be performed on a multi-gram scale, and pure products are isolated by simple filtration without workup. Interestingly, the complementary two-step procedure from cotarnine halide salts gives the Mannich products in good yields. The scope was elaborated to 9-bromocotarnine salts to access a range of 9-bromonoscapine-derived analogues. The methodology has been developed considering the structural similarity of cotarnine derivatives to noscapinoids, which represent an emerging class of microtubule-modulating anticancer agents.

Starting from suitably substituted homophthalic acids, total synthesis of titled alkaloids have been demonstrated in very good yields. The obtained natural products laudanosine and romneine were utilized to accomplish synthesis of two isoquinoline-based alkaloids glaucine and dicentrine. Base-induced selective generation of two different types of benzylic carbanions, their coupling reactions with 3,4-dimethoxybenzyl mesylate, and the regioselective iodination followed by intramolecular aryl-aryl coupling reactions to form the fused biaryl systems were the strategic steps.

Efficient and rapid preparations of carbamoyl chlorides and unsymmetrical ureas from tertiary amines and phosgene or its safe equivalent triphosgene [bis(trichloromethyl)carbonate, BTC] are described. First, the reaction of stoichiometric amounts of phosgene with secondary amines was revisited, and it was shown that the formation of carbamoyl chlorides in high yields required careful adjustments of experimental conditions and the use of pyridine as an HCl scavenger. A phosgene-mediated dealkylation of triethylamine was observed when this base was used instead of pyridine. Taking advantage of this observation, a strategy of synthesis of carbamoyl chlorides from tertiary amines and phosgene has been developed. N-Alkyl-N-benzyl(substituted)tetrahydroisoquinolines, -piperazines, -piperidines, or -anilines were treated with stoichiometric amounts of phosgene (or BTC) in CH2Cl2. Tertiary amines bearing electron-enriched benzyl group(s) afforded carbamoyl chlorides in excellent yields and without any contamination by symmetrical ureas. Subsequent additions of primary or secondary amines to these carbamoyl chlorides produced unsymmetrical ureas in single-pot and high-yielding operations. This methodology was applied in 11C-chemistry. From [ 11C]phosgene, a common precursor used in the preparation of radiotracers for positron emission tomography, a rapid and efficient synthesis of 11C-carbamoyl chlorides and 11C-unsymmetrical ureas derived from tetrahydroisoquinoline and piperazine is described. The first example of 11C-amide formation from the reaction of a 11C-carbamoyl chloride and an organometallic (cyanocuprate or a Grignard reagent in the presence of a nickel catalyst) is also presented.

Photosynthesis is an efficient mechanism for converting solar light energy into chemical energy. We report on a strategy for the aerobic photocyanation of tertiary amines with visible and near-infrared (NIR) light. Panchromatic sensitization was achieved by functionalizing TiO2 with a 2-methylisoquinolinium chromophore, which captures essential features of the extended ?-system of 2,7-diazapyrenium (DAP2+) dications or graphitic carbon nitride. Two phenolic hydroxy groups make this ligand highly redox-active and allow for efficient surface binding and enhanced electron transfer to the TiO2 surface. Non-innocent ligands have energetically accessible levels that allow redox reactions to change their charge state. Thus, the conduction band is sufficiently high to allow photochemical reduction of molecular oxygen, even with NIR light. The catalytic performance (up to 90% chemical yield for NIR excitation) of this panchromatic photocatalyst is superior to that of all photocatalysts known thus far, enabling oxidative cyanation reactions to the corresponding alpha-cyanated amines to proceed with high efficiency. The discovery that the surface-binding of redox-active ligands exhibits enhanced light-harvesting in the red and NIR region opens up the way to improve the overall yields in heterogeneous photocatalytic reactions. Thus, this class of functionalized semiconductors provides the basis for the design of new photocatalysts containing non-innocent donor ligands. This should increase the molar extinction coefficient, permitting a reduction of nanoparticle catalyst concentration and an increase of the chemical yields in photocatalytic reactions.

The hydrochlorides of molecular segments of apomorphine [2 (3′,4′ dihydroxybenzyl) 1,2,3,4 tetrahydroisoquinoline, 2 (3′,4′ dihydroxybenzyl) piperidine, and 1,2,3,4 tetrahydroisoquinoline with their respective N methyl and N n propyl homologs] and N,N dialkylated dopamine compounds were synthesized and studied for LD50 in intact mice; stereotypy in intact mice; curving of the body in unilaterally caudectomized mice; rotation in 6 hydroxydopamine lesioned rats, and activation of adenylate cyclase in homogenates of mouse caudate nuclei. Instead of dopaminergic effects 1 (3′,4′ dihydroxybenzyl) 2 methyl 1,2,3,4, tetrahydroisoquinoline and 2 methyl 1,2,3,4, tetrahydroisoquinoline showed cholinergic ones. These effects were blocked in atropine pretreated animals. Of the N,N dialkylated dopamine compounds synthesized, the N n propyl N n butyldopamine ranked in all tests as the strongest dopamine receptor agonist and N methyl N n propyldopamine as the weakest. In contrast, N,N dimethyldopamine and 1 (3,4 dihydroxyphenylethyl) piperidine showed no dopaminergic effects. The effectiveness of the dopaminergic agonists depended on the length of the N alkyl substituents suggesting interactions with hydrophobic regions of the receptor site.
