标题:Synthesis of chiral N-protected-α-substituted-glycine free acids by zinc-mediated addition of organic halide to glycine cation equivalent
发明人：ABOOD NORMAN A; NOSAL ROGER A

摘要:A method is described for synthesis of N-Boc-L-propargylglycine, a key intermediate used in the preparation of high-potency, orally-active renin inhibitors. This method involves reaction of an organic halide with a glycine cation equivalent, such as methyl N-Boc-2-acetoxyglycine, in the presence of zinc dust to give Boc-protected amino acid derivatives in high yield. Typically useful organic halides are allylic, benzylic and propargylic halides. Resolution of methyl N-Boc-propargylglycine with alpha -chymotrypsin provides N-Boc-L-propargylglycine in high yield.

摘要:The invention provides an amphiphilic coating for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, comprising a hydrophilic chemical structure and a lipophilic group, wherein said peptides and small molecular compounds differ from spot to spot from each other in the chemical structure, characterized in that said amphiphilic coating possesses low wettability to polar aprotic solvents used in the array synthesis; said amphiphilic coating possessing low wettability is designed that it can be converted to a coating possessing high wettability by hydrolysis of the lipophilic group; and said amphiphilic coating comprises an amino group for the reaction with an electrophilic reagent. The invention further provides a solid support comprising said amphiphilic coating and a method for method for the direct and rapid synthesis of an array of peptides and small molecular compounds on a planar surface of a solid support, wherein said planar surface of a solid support comprises said amphiphilic coating. Said method includes the enhancing of the wettability of a glass surface to organic solvents to realize automated on-demand biomolecular array synthesis comprising both, peptides and small molecular compounds. The amphiphilic surface can be switched to a hydrophilic surface, resulting in high density arrays suitable for protein- and cell-based screening.
