Synthesis and structure–activity relationships of aristoyagonine derivatives as brd4 bromodomain inhibitors with x-ray co-crystal research

Epigenetic regulation is known to play a key role in progression of anti-cancer therapeutics. Lysine acetylation is an important mechanism in controlling gene expression. There has been increasing interest in bromodomain owing to its ability to modulate t

Controlling the Substitution Pattern of Hexasubstituted Naphthalenes by Aryne/Siloxyfuran Diels–Alder Additions: Regio- and Stereocontrolled Synthesis of Arizonin C1 Analogs

3,4-Dimethoxybenz-1-yne and 2-siloxylated furans without or with a bromine atom at C-3 undergo Diels–Alder reactions with orientational selectivity. Hydrolysis furnished a bromine-free or a bromine-containing naphthalene, respectively. Bromination of the former provided a regioisomer of the latter. Either of the two compounds was processed to give a variety of unnatural naphthoquinonopyrano-γ-lactones. This occurred by a succession of (1) Heck coupling, (2) asymmetric dihydroxylation, (3) oxa-Pictet–Spengler cyclization, and (4) oxidation. The fifteen monomeric naphthoquinonopyrano-γ-lactone structures that we prepared resemble the natural product (–)-arizonin C1 or its C-5 epimer. Accordingly, they represent hexasubstituted naphthalenes likewise. The sixteenth naphthoquinonopyrano-γ-lactone that we synthesized is a kind of dimer. Its moieties are bridged differently than those in naturally occurring naphthoquinonopyrano-γ-lactone dimers.

Collective asymmetric synthesis of (-)-Antofine, (-)-cryptopleurine, (-)-tylophorine, and (-)-tylocrebrine with tert- butanesulfinamide as a chiral auxiliary

A collective asymmetric synthesis of phenanthroindolizidine and phenanthroquinolizidine alkaloids (-)-antofine, (-)-cryptopleurine, (-)-tylophorine, and (-)-tylocrebrine was achieved by means of a reaction sequence involving efficient generation of chiral homoallylic amine intermediates by asymmetric allylation of the corresponding tert-butanesulfinyl imine. From these intermediates, the pyrrolidine and piperidine rings were constructed by means of an intramolecular SN2 substitution reaction and a ring-closing metathesis reaction, respectively. The unusual C5-methoxy-substituted phenanthrene moiety of (-)-tylocrebrine was generated by means of an InCl3-catalyzed cycloisomerization reaction of an o-propargylbiaryl compound.
