Pd(ii)-catalyzed ligand controlled synthesis of methyl 1-benzyl-1H-indole- 3-carboxylates and bis(1-benzyl-1H-indol-3-yl)methanones

A simple change of ligand and solvent allows controlled, effective switching between cyclization-carbonylation and cyclization-carbonylation- cyclization-coupling (CCC-coupling) reactions of 2-alkynylanilines catalyzed by palladium(ii). The use of a [Pd(tfa)2(box)] catalyst in iPrOH afforded symmetrical ketones bearing two indoles in good yields; replacing the catalyst and solvent with Pd(tfa)2 and DMSO-MeOH led to the formation of methyl 1-benzyl-1H-indole-3-carboxylates in good yields.

C-3 functionalization of indole derivatives with isoquinolines

The literature on the syntheses of substituted 1-(indol-3-yl)-1,2,3,4-tetrahydroisoquinoline derivatives is reviewed. Two main synthetic procedures have been applied for these syntheses. One is cross-dehydrogenative coupling, which can furnish various C-3 functionalized indoles; oxidants and/or catalysts are usually needed. Another convenient synthetic method is the aza-Friedel-Crafts alkylation of indole derivatives with dihydroisoquinoline, the main advantage of this being the direct catalyst-free coupling under mild experimental conditions. The review also considers miscellaneous reactions, where the isoquinoline skeleton is achieved in one of the final steps of the synthesis.

Discovery and SAR of 2-aminothiazole inhibitors of cyclin-dependent kinase 5/p25 as a potential treatment for Alzheimer’s disease

High-throughput screening with cyclin-dependent kinase 5 (cdk5)/p25 led to the discovery of N-(5-isopropyl-thiazol-2-yl)isobutyramide (1). This compound is an equipotent inhibitor of cdk5 and cyclin-dependent kinase 2 (cdk2)/cyclin E (IC50 = ca. 320 nM). Parallel and directed synthesis techniques were utilized to explore the SAR of this series. Up to 60-fold improvements in potency at cdk5 and 12-fold selectivity over cdk2 were achieved.

Cholecystokinin antagonists: (R)-tryptophan-based hybrid antagonists of high affinity and selectivity for CCK-A receptors

The intriguing structural similarities of glutamic acid based cholecystokinin (CCK) antagonists (A-64718 and A-65186) and the benzodiazepine CCK antagonist MK-329 (L-364,718) have been reported. Efforts to include the weak CCK antagonist benzotript into this construct utilizing a similar approach have resulted in a novel series of benzotript-based hybrid antagonists N(alpha)-(3′-quinolylcarbonyl)-(R)-tryptophan di-n-pentylamide (9, A-67396), N(alpha)-(4′,8′-dihydroxy-2′-quinolylcarbonyl)-(R)-tryptophan di-n-pentylamide (23, A-70276), and N(alpha)-(3′-quinolylcarbonyl)-(R)-5′-hydroxytryptophan di-n-pentylamide (36, A-71134) which possess respectively binding affinities of 23, 21, and 11 nM for the pancreatic CCK-A receptor and which inhibit CCK8-induced amylase secretion. Compound 9 possesses a selectivity of > 500-fold for the pancreatic CCK-A receptor over the CCK-B receptor.

Development of a Cross-Conjugated Vinylogous [4+2] Anionic Annulation and Application to the Total Synthesis of Natural Antibiotic (¡À)-ABX

The cross-conjugated vinylogous [4+2] anionic annulation has been newly developed, the cascade process of which has a high preference for regiochemical control and chemoselectivity, giving rise to exclusively Michael-type adducts in moderate to high yields (up to 94 %, 35 examples). By making use of this approach as a key operation, the first total synthesis of natural antibiotic ABX, in racemic form, has been successfully achieved in a concise 7-step sequence with an overall yield of about 20 %.
