Abstract: A method for synthesizing enantiomerically enriched chemical intermediates with predetermined chirality is described. The method comprises formation of a pseudoephedrine amide, followed by stereoselective alkylation at the alpha carbon. The chiral auxiliary can then be cleaved off, affording chiral end products useful for further transformations. The enantiomeric enrichment of the chiral end products may exceed 98%, and the chiral auxiliary can be recovered. Novel amides of pseudoephedrine used in this method are also disclosed.

Abstract: N-monosubstituted neoalkanamides of 11 to 14 carbon atoms wherein the substituent on the amide nitrogen is cyclic (aromatic or cycloaliphatic, such as aryl or cycloalkyl) and of at least five carbon atoms, have been discovered to be insect repellent, providing that any aromatic substituent is unsubstituted at the ortho position and that when the neoalkanoyl moiety is pivaloyl the total number of carbon atoms in the N-cyclic neoalkanamide is at least 12. Such neoalkanamides are useful as repellents against cockroaches, including American, German and Oriental cockroaches, and are also effective against mosquitoes (both Anopheles and Aedes), black flies and carpenter ants, and to some extent against deer ticks. They may be applied to areas, locations and items which are desirably to be kept free of such insects, with applications being direct or of solutions or emulsions thereof, preferably by spraying, or in detergent compositions or other products to be applied to such areas, etc.
