Dynamic combinatorial chemistry with hydrazones: Libraries incorporating heterocyclic and steroidal motifs

We expand the possibilities in hydrazone based dynamic combinatorial chemistry with a series of new building blocks incorporating heterocyclic motifs. The synthetic procedure allows efficient access to building blocks with the general structure (MeO)2CH-Heterocycle-C(O)NHNH2, originating from heterocycles with an amine and an ester functionality. The equilibrium distribution of macrocyclic N-acyl hydrazones formed upon deprotection of the building blocks with TFA in organic solvents is reported. The mixing behaviour of these heterocycle-based building blocks with our cholate-based building blocks is described, particularly the observation of kinetic intermediates that disappear following ‘proof-reading’.

Base-Dependent Divergent Annulation of 4-Chloro-3-formylcoumarin and Tetrahydroisoquinoline: Application to the Synthesis of Isolamellarins and Hydroxypyrrolones

A series of pyrrolo[2,1-a]isoquinoline and coumarin-fused pentacyclic derivatives were synthesized via base-mediated divergent annulation of 4-chloro-3-formylcoumarin and tetrahydroisoquinoline as a key step. This method was then extended to the preparation of isolamellarins A and B (isolamellarin G trimethyl ether). When exposed to UV light, the pyrrolo[2,1-a]isoquinoline- and coumarin-fused pentacycles B were found to undergo aerobic oxidation to give the corresponding hydroxypyrrolones.

Synthesis and antitumour activity of beta-hydroxyisovalerylshikonin analogues

A series of novel beta-hydroxyisovalerylshikonin analogues bearing oxygen-containing substituents at the side-chain hydroxyl of shikonin were designed and synthesized. The cytotoxicities of these compounds were evaluated in vitro against multi-drug resistant (MDR) cell lines DU-145 and HeLa. Most compounds exhibited significant inhibitory activity on both cell lines. The structure-activity relationship showed the analogues with ether substituents displayed the most potent antitumour activity and selective cytotoxicity towards DU-145. Among the compounds with ether substituents, increasing the steric hindrance in the carbon bearing beta-hydroxyl or replace the beta-hydroxyl with acetoxy or methoxy would lead to the decline of cytotoxicity.

Catalyst-Free Transamidation of Aromatic Amines with Formamide Derivatives and Tertiary Amides with Aliphatic Amines

A simple catalyst- and promoter-free protocol has been developed for the transamidation of weakly nucleophilic aromatic amines with formamide derivatives and low-reactivity tertiary amides with aliphatic amines. This strategy is advantageous because no catalyst or promoters are needed, no additives are required, separation and purification is easy, and the reaction is scalable. Significantly, this strategy was further applied to synthesize several pharmaceutical molecules on a gram scale, and excellent yields were achieved.

Cholinergic effects of molecular segments of apomorphine and dopaminergic effects of N,N dialkylated dopamines

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.

Total Synthesis of Tetrahydroisoquinoline-Based Bioactive Natural Products Laudanosine, Romneine, Glaucine, Dicentrine, and Their Unnatural Analogues Isolaudanosine and Isoromneine

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.
