    • 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.
    • 本发明描述了通过形成液体反应介质和携带多个式(A1)或(B1)部分的固相反应产物的混合物来制备包含共价键合的异羟肟酸基-CONHOH的所需合成产物的方法, :其中X是所需合成产物的残留的非羟肟酸盐部分结构,P1是氢或氨基保护基,P2是氢或羟基保护基,并且指定为(a)的键共价连接部分(A1 )或(B1)与固体底物的残留物; 通过在所得混合物中切割指定为(a)的键; 并通过将所得液体反应相与所得反应固体分离以回收所需的合成产物。
