48 - 100Asymmetric Diels-Alder Reactions of Chiral 1-Amino-3-siloxy-1,3-butadiene: Application to the Enantioselective Synthesis of (-)-α-Elemene. — The use of the chiral butadiene (I) in cycloaddition reactionswith various dienophiles represents an important advance to available methodsfor the asymmetric synthesis of cyclohexenone species. An application ofthis methodology is demonstrated by use of (III) in the synthesis of the titleterpene (XIV). — (KOZMIN, S. A.; RAWAL, V. H.; J. Am. Chem. Soc. 119(1997) 30, 7165-7166; Dep.
