Inhibitors of Sir2: Evaluation of Splitomicin Analogues
Posakony, Jeff,Hirao, Maki,Stevens, Sam,Simon, Julian A.,Bedalov, Antonio
, p. 2635 - 2644 (2004)
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.

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

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

New Syntheses of Coumarins
Panetta, Jill A.,Rapoport, Henry
, p. 946 - 950 (2007/10/02)
New, versatile coumarin syntheses have been developed which are based on the Claisen rearrangement of allylic or propargylic aryl ethers in which the allylic or propargylic α-carbon is further oxygenated.One proceeds by first ester exchange to the aryl dialkyl orthoacrylate which then thermally rearranges.Hydrolytic treatment gives the o-hydroxydihydrocinnamic acid from which the coumarin is obtained by ring closure and dehydrogenation.In parallel fashion, an orthopropiolate may be used, eliminating the dehydrogenation step.These processes have the adventage ofavoiding the drastic acid conditions and orientation limitations of previous coumarin syntheses.They have been applied to syntheses in good yields of coumarins obtainable by previous methods in very poor yield or not at all.
