摘要: A compound of the formula ##STR1## is disclosed. X is selected from the group consisting of aryl, alkyl, imte ester, imino ester, amidine, azide, isocyanate, and dithiocarbonate. R' is a group selected from the group consisting of groups containing a hydroxyl moiety, groups containing a protected hydroxyl moiety, and groups containing an O-linked sugar. G is a carbon chain of 0-10 carbons and R is not a methyl group and is a group capable of removal under conditions compatible with glycopeptide synthesis. In a preferred form the compound, R is selected from the group consisting of benzylic or allyl groups and X is CPh.sub.2. A method of forming a glycocide from the compound is also disclosed.

摘要: A chiral ligand system for transition or main group metal catalysts is disclosed. These ligands can be readily synthesized using inexpensive amino acids and diamines as starting materials. Several different transition or main group metals have been inserted into the ligands. The ligands have been shown to have a tetradhedral distortion that may contribute to enhanced chiral transfer from the catalyst to the substrate in chemical modifications of olefins and other reactive substrates. These catalysts have been demonstrated to be effective in catalyzing epoxidation of a variety of substrates.

摘要: Amphipathic glycopeptides, the amino acid sequence of which comprises an N-terminal opioid message sequence, a C-terminal helical address sequence, and a linker sequence between the message sequence and the helical address sequence, where the C-terminal helical address sequence has a length of nine amino acids, and at least one of the amino acid residues of the peptide is glycosylated. The peptides are useful for relieving pain, providing analgesia and treating anxiety, depression, obesity, anorexia nervosa, phobias, schizophrenia, Parkinson's disease and Alzheimer's disease.
