标题:Synthesis of hydroxamic acid derivatives
发明人：FLOYD CHRISTOPHER DAVID; LEWIS CHRISTOPHER NORMAN
权利人:BRITISH BIOTECH PHARM
摘要:The present invention describes processes for preparing desired synthetic products that comprise a covalently bonded hydroxamic acid group -CONHOH by forming a mixture of a liquid reaction medium and a solid phase reaction product that carries a plurality of moieties of formula (A1) or (B1):where X is a residual, non-hydroxamate partial structure of the desired synthetic product, P1 is hydrogen or an amino-protecting group, P2 is hydrogen or a hydroxyl protecting group, and the bond designated (a) covalently links the moieties (A1) or (B1) to the residue of a solid substrate; by cleaving the bond designated (a) in the resultant mixture; and by separating the resultant liquid reaction phase from the resultant reaction solids to recover the desired synthetic product.
