Abstract:
The present invention provides methodology for carbon-nitrogen bond formation via vinyl or aryl amination. In the process of the invention, an sp2 hybridized radical is reacted with an azomethine moiety to form pyrrolidine and indole compounds. The methodology provides a facile process for the synthesis of compounds having the pyrrolidine or indole subunit and is especially advantageous for compounds having acid or base labile functional groups andor is comprised of chiral centers susceptible to acidbase epimerization.

Abstract:
The subject invention involves a solid-phase process for the synthesis of indole compounds comprising the steps: (a) treating an amino resin with diketene to provide a resin-bound acetoacetamide; (b) treating the product from Step (a) with a primary amine in the presence of a dehydrating agent to provide a resin-bound enaminone; (c) treating the product from Step (b) with a 1,4-benzoquinone, and releasing the resulting indole product from the resin.
Abstract:
Fluorinated alkyl compounds may be used as reaction intermediates or reaction products in polymerizing amino acid structures into peptides. Fluorinated methyl groups have been found to be particularly useful. A compound having a fluorinated methyl group such as that set forth below: 1 wherein R is selected from the group consisting of: alkyls, hydrogen, aryls, aromatic compounds, amines, sulfur-containing alkyl groups, sulfur-containing aryl groups, and heterocyclic compounds may be utilized alone, or reacted in combination with other amino acids, to form a dipeptide, or polypeptide.
Abstract:
This invention relates to the synthesis of novel cationic, amphiphilic lipids and their application as gene transfer vehicles in vitro and in vivo. For this a series of different lipids (diglycerides, steroids) were synthesized by modification with variable cationic molecules (amino acids, biogenic amines). Compounds of this kind are, due to their capability of producing complexes with polynucleotides (DNA, RNA, Antisense oligonucleotides, ribozymes etc) suitable as vectors for gene transfer (transfection).
