We recently developed a novel chiral catalyst-directed dynamic kinetic diastereoselective acylation of hemiacetals for the synthesis of carbohydrates. In this update, we describe a catalytic method for the dynamic kinetic enantioselective acylation of 2-c
Chiral Hypervalent Organoiodine-Catalyzed Enantioselective Oxidative Spirolactonization of Naphthol Derivatives
Uyanik, Muhammet,Yasui, Takeshi,Ishihara, Kazuaki
, p. 11946 - 11953 (2017/11/24)
Highly enantioselective oxidative dearomatization of 2-naphthol derivatives was achieved for the first time by using conformationally flexible organoiodine catalysts derived from 2-aminoalcohol as a chiral source. Moreover, with the use of these catalysts

Paragraph 0106, (2014/01/23)
An optically active spirolactone compound is highly enantioselectively produced by using an iodoarene derivative which can be synthesized easily and which is not racemized easily. [Solution] A hypervalent iodine compound precursor (iodoarene derivative) w

Naphthol compounds bearing a pendant α,β-unsaturated ester undergo a copper(I)-catalyzed asymmetric conjugate addition/copper(II)-mediated intramolecular oxidative coupling to afford benzofused spirocyclic cyclohexenones (see scheme). This one-pot strategy results in two new carbon-carbon bonds and three contiguous stereocenters. The products contain a high degree of functionality and molecular complexity.
Anionic alternating copolymerization of epoxide and six-membered lactone bearing naphthyl moiety
Sudo, Atsushi,Zhang, Yuan,Endo, Takeshi
experimental part, p. 619 - 624 (2012/01/13)
This article describes the anionic copolymerization of glycidyl phenyl ether (GPE) and 1,2-dihydro-3H-naphtho[2,1-b]pyran-3-one (DHNP), a six-membered aromatic lactone bearing naphthyl moiety. The copolymerization proceeded in a 1:1 alternating manner, to
Methods for inhibiting deacetylase activity

Page/Page column 13, (2008/06/13)
A method for identifying a compound that inhibits the NAD+-dependent deacetylase activity of a SIR2 protein is disclosed. These compounds are useful for the treatment of cancers and other diseases, through the activation of silenced genes, through the promotion of apoptosis in cancerous cells, and through the inhibition of transcriptional repressor activity in oncogenes.
Direct functionalization of arenes by primary alcohol sulfonate esters catalyzed by gold(III)
Shi, Zhangjie,He, Chuan
, p. 13596 - 13597 (2007/10/03)
Alkylation of arenes by primary alcohol triflate or methanesulfonate esters can be efficiently catalyzed by AuCl3 with silver triflate. Copyright
Inhibitors of Sir2: Evaluation of Splitomicin Analogues
Posakony, Jeff,Hirao, Maki,Stevens, Sam,Simon, Julian A.,Bedalov, Antonio
, p. 2635 - 2644 (2007/10/03)
Splitomicin (1) and 41 analogues were prepared and evaluated in cell-based Sir2 inhibition and toxicity assays and an in vitro Sir2 inhibition assay. Lactone ring or naphthalene (positions 7-9) substituents decrease activity, but other naphthalene substitutions (positions 5 and 6) are well-tolerated. The hydrolytically unstable aromatic lactone is important for activity. Lactone hydrolysis rates were used as a measure of reactivity; hydrolysis rates correlate with inhibitory activity. The most potent Sir2 inhibitors were structurally similar to and had hydrolysis rates similar to 1.
A Facile Synthesis of Dihydronaphthopyrans
Ranade, Anup A.,Joseph, Augustine R.,Kumbhar, Virendra B.,Paradkar, Madhusudan V.
