Microwave-enhanced bismuth triflate-catalyzed epoxide opening with aliphatic amines
Ollevier, Thierry,Nadeau, Etienne
, p. 1546 - 1550 (2008)
In the presence of a catalytic amount of Bi(OTf)3·4H2O and under microwave irradiation, neat mixtures of epoxides and amines afforded smoothly the corresponding 2-amino alcohols. A wide variety of aliphatic amines were reacted with cycloalkene oxide, styrene oxide, and stilbene oxide. The reaction proceeded rapidly and afforded the 2-amino alcohols in high up to quantitative yields. All products could be obtained without aqueous work-up by simple filtration.
Three-dimensional {Co3+-Zn2+} and {Co 3+-Cd2+} networks originated from carboxylate-rich building blocks: Syntheses, structures, and heterogeneous catalysis

The present work shows the utilization of Co3+ complexes appended with either para- or meta-arylcarboxylic acid groups as the molecular building blocks for the construction of three-dimensional {Co 3+-Zn2+} and {Co3+-Cd2+} heterobimetallic networks. The structural characterizations of these networks show several interesting features including well-defined pores and channels. These networks function as heterogeneous and reusable catalysts for the regio- and stereoselective ring-opening reactions of various epoxides and size-selective cyanation reactions of assorted aldehydes.

Bismuth triflate-catalyzed mild and efficient epoxide opening by aromatic amines under aqueous conditions
Ollevier, Thierry,Lavie-Compin, Guillaume
, p. 49 - 52 (2007/10/03)
Bismuth triflate catalyzes the ring opening of epoxides with aromatic amines under aqueous conditions. The reaction proceeds rapidly and affords the corresponding β-amino alcohols in excellent yields.
Zirconium sulfophenyl phosphonate as a heterogeneous catalyst in the preparation of β-amino alcohols from epoxides
Curini, Massimo,Epifano, Francesco,Marcotullio, Maria Carla,Rosati, Ornelio
, p. 4149 - 4152 (2007/10/03)
A convenient method for the ring opening of epoxides by aromatic amines, catalysed by zirconium sulfophenyl phosphonate in solvent-free conditions, is described.
2(1H)-Quinolinone derivatives as novel anti-arteriostenotic agents showing anti-thrombotic and anti-hyperplastic activities
Koga, Yasuo,Kihara, Yoshito,Okada, Minoru,Inoue, Yoshihiro,Tochizawa, Shirou,Toga, Kazuyuki,Tachibana, Kazue,Kimura, Yukio,Nishi, Takao,Hidaka, Hiroyoshi
, p. 1471 - 1476 (2007/10/03)
In order to search for anti-arteriostenotic agents, a series of 2(1H)- quinolinone derivatives was synthesized and evaluated for anti-thrombotic activity and for anti-hyperplastic activity. From this series, (-)-6-[3-[3- cyclopropyl-3-[(1R,2R)-2-hydroxycycyclohexyl]ureido]propoxy]-2(1H)- quinolinone (1p, OPC-33509) was selected as the best candidate by balancing the efficacy on anti-thrombosis and anti-hyperplasia.
