Synthesis of Unsymmetrical 1,4-Dicarbonyl Compounds by Photocatalytic Oxidative Radical Additions

Herein we report a photocatalytic oxidative radical addition reaction for the synthesis of unsymmetrical 1,4-dicarbonyl compounds. This reaction utilizes a desulfurization process to generate electrophilic radicals, which add to α-halogenated alkenes and undergo further oxidation to deliver 1,4-dicarbonyl compounds. This mild and highly efficient method provides a valuable alternative to known strategies.

Intermolecular Phosphite-Mediated Radical Desulfurative Alkene Alkylation Using Thiols

We report herein the development of a S atom transfer process using triethyl phosphite as the S atom acceptor that allows thiols to serve as precursors of C-centered radicals. A range of functionalized and electronically unbiased alkenes including those containing common heteroatom-based functional groups readily participate in this reductive coupling. This process is driven by the exchange of relatively weak S-H and C-S bonds of aliphatic thiols for C-H, C-C, and S-P bonds of the products formed.

Site-Selective and Enantioselective α,β,γ-Functionalization of 5-Alkylidenefuran-2(5 H)-ones: A Route to Polycyclic γ-Lactones

A new strategy for a direct α,β,γ-functionalization of the γ-lactone framework in the corresponding 5-alkylidenefuran-2(5H)-ones is reported. The developed approach is based on a stereocontrolled cascade reaction with 2-mercaptocarbonyl compounds proceedi

Br?nsted-base-catalyzed remote cascade reactivity of 2,4-dienones-asymmetric synthesis of tetrahydrothiophenes

This study demonstrates that the remote cascade functionalization of 2,4-dienones can be realized by employing Br?nsted base catalysis. The developed cascade involving 1,6-addition followed by the intramolecular aldol reaction provides a straightforward a

Trithiocarbonates as a novel class of HDAC inhibitors: SAR studies, isoenzyme selectivity, and pharmacolozgical profiles

Inhibitors of histone deacetylases (HDAC) are currently developed for the treatment of cancer. These include compounds with a sulfur containing head group like depsipeptide, alkylthiols, thiocarboxylates, and trithiocarbonates with a carbonyl group in the α-position. In the present investigation, we report on the synthesis and comprehensive SAR analysis of HDAC inhibitors bearing a tri- or dithiocarbonate motif. Such trithiocarbonates are readily accessible from either preformed or in situ prepared α-halogenated methylaryl ketones. A HDAC isotype selectivity and a substrate competitive mode-of-action is shown for defined analogues. Exploration of the head group showed the necessity of the dithio-α-carbonyl motif for potent HDAC inhibition. Highly potent, substrate competitive HDAC6 selective inhibitors were identified (12ac:IC50 = 65 nM and Ki = 110 nM). Trithiocarbonate analogues with an aminoquinoline-substituted pyridinyl-thienoacetyl cap demonstrate a cytotoxicity profile and potency comparable to that of suberoylanilide hydroxamic acid (SAHA) as an approved cancer drug.

Trithiocarbonates-Exploration of a new head group for HDAC inhibitors

Inhibition of histone deacetylases class I/II enzymes is a new, promising approach for cancer therapy. In the present study, we disclose a new structural class of HDAC inhibitors with the trithiocarbonate motif. A clear structure-activity-relationship was obtained for the cap-linker motif and the putative Zn2+ complexing head group. Selected analogs display potent inhibition of HDAC enzymatic activity and a cellular potency comparable to that of suberoylanilide hydroxamic acid (SAHA), recently approved for treatment of patients with advanced cutaneous T-cell lymphoma.

A new approach for the conversion of thiohydantoin to hydantoin derivatives

The reaction of thiohydantoins with 1-(bromoacetyl)benzenes afforded the corresponding hydantoin derivatives and 1-(mercaptoacetyl)benzenes instead of the expected oxoimidazothiazoles.
