Parsons, Philip J.,Charles, Mark D.,Harvey, Darren M.,Sumoreeah, L. Ravi,Shell, Adrian,Spoors, Grant,Gill, Adrian L.,Smith, Steve
, p. 2209 - 2211 (2007/10/03)
An approach to the galanthamine ring system is reported, which utilises an intramolecular Heck reaction to establish the benzofuran ring system present in both galanthamine and morphine.
A mild and effective method for the transesterification of carboxylic acid esters
Baumhof, Patrick,Mazitschek, Ralph,Giannis, Athanassios
, p. 3672 - 3674 (2007/10/03)
An extraordinarily versatile transesterification of simple or highly functionalized esters of aliphatic and aromatic carboxylic acids in high yields is catalyzed by dibutyltin oxide [Eq. (1)]. The reaction is compatible with several functional groups, for example, acetals, ketals, aliphatic bromides, enol ethers, urethanes, as well as free hydroxy, phenolic, and amino groups, and even with water.
AN ECONOMICAL DIELS-ALDER STRATEGY FOR THE SYNTHESIS OF DAPHNIPHYLLUM ALKALOIDS
Orban, John,Turner, John V.
, p. 2697 - 2700 (2007/10/02)
A convergent and essentially self-consistent strategy, featuring an unusual Diels-Alder reaction has been devised for the stereo-controlled synthesis of a logical tetracyclic precursor 21 to daphniphyllum alkaloids.
Organometallic Compounds in Organic Synthesis. Part 13. Stereoselectivity of Complexation of Cyclohexadiene Esters
Bandara, B. M. Ratnayake,Birch, Arthur J.,Raverty, Warwick D.
, p. 1755 - 1762 (2007/10/02)
Complexation of cyclohexadienes with Fe(CO)3 as the entering group are subject to classical steric hindrance by alkyl groups, but CO2R and related groups introduce a competing factor because they favour sterically the entering group, probably through an i
