1	A new system for catalytic asymmetric epoxidation Rassias, Gerasimos A. January 1999 (has links) This thesis concerns the catalytic asymmetric synthesis of epoxides. An introduction highlights the utility of chiral epoxides in asymmetric synthesis. The important methods that have been developed towards the construction of this influential functional group are also described. 547
2	Reactions of Anions of Cyclic Oximes, Oxime Ethers, and Chiral Imines Maloney, John R. 08 1900 (has links) The purpose of this investigation is to examine reactions of anions of oximes, oxime ethers and imines with acylating agents and other electrophiles. It is also an attempt to utilize the phenomenon of geometrical enantiomeric isomerism, in which absolute configuration is determined by double bond geometry, and the concept of regiospecific anion formation, also determined by double bond geometry, for stereospecific synthesis of tropinone derivatives. geometrical enantiomeric isomerism anions of oximes oxime ethers chiral imines Anions.
