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.

, 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.
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
