• The Synthesis of Phosphaisocoumarins by Cu(I)-Catalyzed Intramolecular Cyclization of <i>o</i>-Ethynylphenylphosphonic Acid Monoesters

  日期：2003.12.1

  Cu(I)-catalyzed intramolecular cyclization of o-ethynylphenylphosphonic acid monoethyl esters was examined, and a new class of six-membered phosphorus heterocycles was formed with high regioselectivity and good yields. The present reaction is the first example of intramolecular addition of P-OH to alkynes, which provides a convenient way to synthesize novel phosphorus heterocycles having potential

  日期：2005.10

  A series of 4-halophosphaisocoumarins were prepared with high regioselectivity in good to excellent yields under mild conditions by the reaction of 2-(1-alkynyl)phenylphosphonic acid diesters with I2 in CHCl3 or ICl in CH2Cl2, or by the reaction of 2-(1-alkynyl)phenylphosphonic acid monoesters with NBS or NCS in DMF. Whether the alkynylphosphonates could cyclize or not was affected by the substituents

  日期：2004.4.1

  4-lodophosphaisocoumarins can be prepared in good yield and with high regioselectivity under mild conditions by the reaction of o-(1-alkynyl)phenylphosphonates with I-2 or ICI. The present reaction represents the first example of a phosphonate iodocyclization onto a C-C triple bond. The resulting iodides can be further elaborated using palladium-catalyzed coupling reactions.

• Phosphaisocoumarins as a new class of potent inhibitors for pancreatic cholesterol esterase

  Due to the importance of pancreatic cholesterol esterase (CEase) as a potential target in atherosclerosis and for the development of hypocholesterolemic agents, there are increasing interests in designing and synthesizing CEase inhibitors. In the present study, we prepared forty-five isocoumarin phosphorus analogues (i.e., phosphaisocoumarins) and investigated the inhibition of these compounds on the CEase. The results showed that some phosphaisocoumarins could act as potent inhibitors of CEase. The most potent inhibitors, compounds 9d, 10a and 12e give IC(50) values of 4.8 mu M, 2.3 mu M and 1.9 mu M, respectively. The inhibition mechanism and kinetic characterization studies indicate that they are reversible competitive inhibitors. (C) 2010 Published by Elsevier Masson SAS.
