Stilbenes are biologically active metabolites of plants that have the potential to attenuate a broad range of human diseases. Gramistilbenoids are a class of natural products with a stilbene skeleton, isolated from the bamboo orchid (Arundina graminifolia), and with significant cytotoxicity against cancer cell lines (NB4, A549, SHSY5Y, PC3, and MCF7). These are the first identified naturally occurring diphenylethylenes to possess a hydroxyethyl unit. However, some of these compounds are not abundant in nature, and thus, their synthesis is advantageous. This paper reports the first synthesis of gramistilbenoids A (1), B (2), and C (3), with overall yields of 10, 2, and 8% respectively. These natural products were synthesized using key reactions, such as Horner-Wadsworth-Emmons olefination, Stille coupling, and hydroboration-oxidation.
Synthesis and NMR analysis of a conformationally controlled β-Turn Mimetic Torsion Balance
Lypson, Alyssa B.,Wilcox, Craig S.
, p. 898 - 909 (2017/11/04)
The molecular torsion balance concept was applied to a new conformationally controlled scaffold and synthesized to accurately evaluate pairwise amino acid interactions in an antiparallel β-sheet motif. The scaffold's core design combines (ortho-tolyl)amide and o,o,o′-trisubstituted biphenyl structural units to provide a geometry better-suited for intramolecular hydrogen bonding. Like the dibenzodiazocine hinge of the traditional torsion balance, the (ortho-tolyl)amide unit offers restricted rotation around an N-aryl bond. The resulting two-state folding model is a powerful template for measuring hydrogen bond stability between two competing sequences. The aim of this study was to improve the alignment between the amino acid sequences attached to the upper and lower aromatic rings in order to promote hydrogen bond formation at the correct distance and antiparallel orientation. Bromine substituents were introduced ortho to the upper side chains and compared to a control to test our hypothesis. Hydrogen bond formation has been identified between the NH amide proton of the upper side chain (proton donor) and glycine acetamide of the lower side chain (proton acceptor).

Ruthenium-Catalyzed Hydroarylation and One-Pot Twofold Unsymmetrical C?H Functionalization of Arenes

A methyl phenyl sulfoximine (MPS) is used as a directing group in the ruthenium-catalyzed intramolecular hydroarylation of alkene-tethered benzoic acid derivatives to afford dihydrobenzofurans and indolines in good to excellent yields. A one-pot, unsymmetrical, twofold C?H functionalization involving intramolecular C?C and intermolecular C?C/C?N bond formations is successfully demonstrated by using a single set of catalytic reaction conditions, which is unprecedented thus far. A novel isoquinolone-bearing dihydrobenzofuran is constructed through an unsymmetrical twofold C?H functionalization.

A new family of biisoquinoline chelates
Durola, Fabien,Hanss, David,Roesel, Pirmin,Sauvage, Jean-Pierre,Wenger, Oliver S.
, p. 125 - 135 (2007/10/03)
Four 8,8′-diaryl-substituted 3,3′-biisoquinoline ligands have been synthesized and characterized. The key feature of this new family of chelates is their endotopic but sterically non-hindering nature. All four ligands were made from a common 8-bromoisoquinolin-3-ol precursor; between three and twelve synthetic steps were necessary to obtain the products. The reported synthetic procedures allow for gram-scale production of these biisoquinolines. Wiley-VCH Verlag GmbH & Co. KGaA, 2007.
