Concise synthesis of 2-benzazepine derivatives and their biological activity

Figure Persented: 2-Benzazepines, which are potentially good candidates for new drug therapies to treat skin wounds, were readily prepared from substituted cinnamylamide via an intramolecular Friedel-Crafts reaction. With few steps and effective reactions, the procedure enables a rapid derivatization of 2-benzazepines. Moreover, optically active 4-substituted-2-benzazepines were prepared from chiral alpha-substituted cinnamylamides, which were readily prepared by asymmetric alpha-alkylation of chiral cinnamyl oxazolidinone amides. We have easily prepared a library of more than 20 derivatives and examined the biological activity of the compounds.

Breaking the Base Barrier: An Electron-Deficient Palladium Catalyst Enables the Use of a Common Soluble Base in C-N Coupling

Due to the low intrinsic acidity of amines, palladium-catalyzed C-N cross-coupling has been plagued continuously by the necessity to employ strong, inorganic, or insoluble bases. To surmount the many practical obstacles associated with these reagents, we utilized a commercially available dialkyl triarylmonophosphine-supported palladium catalyst that facilitates a broad range of C-N coupling reactions in the presence of weak, soluble bases. The mild and general reaction conditions show extraordinary tolerance for even highly base-sensitive functional groups. Additionally, insightful heteronuclear NMR studies using 15N-labeled amine complexes provide evidence for the key acidifying effect of the cationic palladium center.

beta2- And beta3-Peptides with Proteinaceous Side Chains: Synthesis and Solution Structures of Constitutional Isomers, a Novel Helical Secondary Structure and the Influence of Solvation and Hydrophobic Interactions on Folding

Enantiomerically pure beta-amino-acid derivatives with the side chains of Ala, Val, and Leu in the 2- or 3-position (beta2- and beta3-amino acids, resp.), as well as with substituents in both the 2- and 3-positions (beta2,3-amino acids, of like-configuration) have been prepared (compounds 8-17) and incorporated (by stepwise synthesis and fragment coupling, intermediates 24-34) into beta-hexa-, beta-hepta-, and beta-dodecapeptides (1-17). The new and some of the previously prepared beta-peptides (35-39) showed NH/ND exchange rates (in MeOH at room temperature) with tau1/2 values of up to 60 days, unrivalled by short chain alpha-peptides. All beta-peptides 1-7 were designed to be able to attain the previously described 31-helical structure (Figs. 1 and 2). CD Measurements (Fig. 4), indicating a new secondary structure of certain beta-peptides constructed of beta2- and beta3-amino acids, were confirmed by detailed NMR solution-structure analyses: a beta2-heptapeptide (2c) and a beta2,3-hexapeptide (7c) have the 31-helical structure (Figs. 6 and 7), while to a beta2/beta3-hexapeptide (4) with alternating substitution pattern H-(beta2-Xaa-beta3-Xaa)3-OH a novel, unusual helical structure (in (D5)pyridine, Fig. 8; and in CD3OH, Figs. 9 and 10) was assigned, with a central ten-membered and two terminal twelve-membered H-bonded rings, and with C=O and N-H bonds pointing alternatively up and down along the axis of the helix (Fig. 11). Thus, for the first time, two types of beta-peptide turns have been identified in solution. Hydrophobic interactions of and hindrance to solvent accessibility by the aliphatic side chains are discussed as possible factors influencing the relative stability of the two types of helices.

Preparation of multisubstituted enamides via rhodium-catalyzed carbozincation and hydrozincation of ynamides

(Chemical Equation Presented) Rhodium-catalyzed carbozincation of ynamides using diorganozinc reagents or functionalized organozinc halides is described.Using a tri(2-furyl)phosphine-modified rhodium catalyst, the reaction course is altered to hydrozincation when diethylzinc is employed as the organozinc reagent. Trapping of the alkenylzinc intermediates produced in these reactions in further functionalization reactions is possible. Collectively, these processes enable access to a range of multisubstituted enamides in stereo- and regiocontrolled fashion.

Pyrazole-Based Acid Ceramidase Inhibitors: Design, Synthesis, and Structure-Activity Relationships

Acid ceramidase (AC) is a lysosomal cysteine amidase responsible for the cleavage of ceramide into sphingosine, which is then phosphorylated to sphingosine 1-phosphate. AC regulates the intracellular levels of ceramide and sphingosine, and AC inhibition may be useful in the treatment of disorders, such as cancer, in which ceramide-mediated signaling may be dysfunctional. Despite their potential experimental and therapeutic value, the number of available small-molecule inhibitors of AC activity remains limited. In the present study is described the discovery of a class of potent pyrazole carboxamide-based AC inhibitors, which were identified using the atomic property field (APF) approach and developed through systematic SAR investigations and in vitro pharmacological characterization. The best compound of this series inhibits AC with nanomolar potency and causes ceramide accumulation and sphingosine depletion in intact G361 proliferative melanoma cells. By expanding the current armamentarium of AC inhibitors, these results should facilitate future efforts to unravel the biology of AC and the therapeutic potential of its inhibition.

Diastereoselective synthesis of D-threo-sphinganine, L-erythro-sphinganine and (?)-spisulosine through asymmetric alpha-hydroxylation of a higher homologue of Garner’s aldehyde

A diastereoselective route to the synthesis of D-threo-sphinganine, L-erythro-sphinganine and (?)-spisulosine from the higher homologue of Garner’s aldehyde prepared from L-aspartic acid is reported. While the starting material contains one of the stereocenters in the target molecules, the other is generated by proline-catalyzed asymmetric alpha-hydroxylation of the aldehyde function. The two diastereomers of sphinganine are prepared from the same starting material and using the same sequence of reactions, but for the proline isomer used as the catalyst. The method described is simple and efficient and can easily be extended for the synthesis of other sphingoid bases.
