A flexible route for the stereoselective synthesis of trisubstituted γ-butyrolactones, namely (+)-blastomycinone and its analogs, is devised by the Sharpless asymmetric epoxidation and the regioselective ring opening reaction with dibutylcopper lithium as
Stereoselective Intramolecular Nitrone Cycloadditions Promoted by an Allylic Stereocenter

, p. 1901 - 1908 (2007/10/02)
A series of intramolecular nitrone cycloadditions to chiral allyl ethers was studied in order to evaluate the influence on the stereochemical outcome exerted by several factors, including the nature of the substituents at the stereocenter and the steric and electronic features of the double bond.A comparison between the stereoselectivity of these reactions and that of related nitrile oxides cycloadditions suggests that they could proceed via similar transition states.
AN OBSERVATION OF DIASTEREOFACE SELECTIVITY IN THERMAL REACTIONS BETWEEN δ-ALKOXYALLYLSTANNANES AND ALDEHYDES
Mortlock, Simon V.,Thomas, Eric J.
, p. 2479 - 2482 (2007/10/02)
The δ-alkoxyallylstannanes (4) and (5) react stereoselectively on heating with p-nitrobenzaldehyde to provide the homoallylic alcohols (14) - (17), with (14) : (15) = 82 : 18; (16) : (17) = 73 : 27
INTRAMOLECULAR NITRILE OXIDE CYCLOADDITION ON CHIRAL OLEFINS : A STEREOCONTROLLED APPROACH TO β-KETOL PRECURSORS.

, p. 2369 - 2380 (2007/10/02)
The intramolecular nitrile oxide cycloaddition reaction on (E) or (Z) olefins featuring a sulphur atom along the carbon chain connecting dipole and dipolarophile occurs with a poor to excellent anti stereoselectivity, which is mainly affected by the subst
