Analogues of Acifran: Agonists of the High and Low Affinity Niacin Receptors, GPR109a and GPR109b
摘要:
Recently identified GPCRs, GPR109a and GPR109b, the high and low affinity receptors for niacin, may represent good targets for the development of HDL elevating drugs for the treatment of atherosclerosis. Acifran, an agonist of both receptors, has been tested in human subjects, yet until recently very few analogs had been reported. We describe a series of acifran analogs prepared using newly developed synthetic pathways and evaluated as agonists for GPR109a and GPR109b, resulting in identification of compounds with improved activity at these receptors.

Efficient access to α,α′-diacetoxy ketones has been developed from ethynylcarbinols and PhI(OAc)2. A plausible mechanism for this was proposed on the basis of experimental studies. The usefulness of α,α′-diacetoxy ketone products has been documented, and glycerol derivatives can be easily synthesized in good yields via a one-potreaction.

Radical Hydro-Fluorosulfonylation of Propargylic Alcohols via Electron Donor–Acceptor Photoactivation
photoactivation of the electrondonor–acceptor (EDA) complex. The reaction avoids the requirement for photocatalysts, bases, hydrogen donor reagents, any other additives, and harsh conditions, enabling the facile synthesis of various functionalized γ-hydroxy (E)-alkenylsulfonyl fluorides. These multifunctional sulfonyl fluorides can be further diversified, providing access to various privileged molecules

Exposure of ethynyl carbinols to oxone/(CF3CO)(2)O in the presence of a catalytic amount of iodobenzene afforded ,-dihydroxy ketones in good yield, which are common structural motifs in natural products and biologically active compounds. Compared with traditional methods, this method is more convenient and avoids using stoichiometric amounts of hypervalent iodine reagents.
