The invention relates to novel silane compounds corresponding to the formula (I) below:
A-E-X (I)
in which:
X represents a silyl group capable of creating a covalent bond after reaction with the hydroxyl or hydride functional groups of a support;
E represents an organic spacer group;
A represents a group chosen from the groups of formulae below:
in which:
Z1 to Z5 independently represent a hydrogen atom or a halogen atom;
Z6 and Z7 represent a group for protecting the phosphonic acid functional group, a hydrogen atom or a monovalent cation;
Z8 to Z12 independently represent a group for protecting the carboxylic acid functional group, a hydrogen atom or a monovalent cation; and
Z13 represents an imidazole, N-hydroxysuccinimide, nitrophenyl, pentafluorophenyl or acid anhydride group.
Use of these silane compounds for functionalizing solid supports and for immobilizing biological molecules on these supports.

the Negishi cross-coupling reaction of organozinc compounds derived from chiral amino acids was extended to electron rich iodoanilines and iodobenzylamines as coupling reagents. The protocol allows the direct modification of serine into phenylalanine derivatives bearing metal ion chelating ligands in their sidechain, such as amino esters 6 and 7. The preparation of metal complex labeled peptides, the
The highly enantioselective copper-catalyzed propargylic amination of propargylic esters with amine hydrochloride salts has been realized for the first time using copper salts with chiral N,N,P-ligands. This method features a broad substrate scope and wide functional group tolerance, generating propargylic amines in good to excellent yields with high enantioselectivities (up to 99% ee). The utility
