The preparation of any compound of the generic structure (I); wherein: R1 and R2 are substituents described in the main text. Cycl- is a group represented by either of the formulae (a) and (b); wherein: R3 to R8, X and Y are substituents described in the main text. The above described compounds may be used for the treatment of cancer. The preparation method consists of coupling of the amine group of phosphynilglycinate with the carboxylic group of an aminoacid, the successively coupling of the above formed compound with the formyl-Cycl derivative, the deprotection of the aminoacid and the formation of dehydro-diketopiperazine employing mild alkaline conditions. The method is extended for the preparation of individual derivatives or libraries of derivatives related to the above described compounds of the general formula (II), employing a solid supported phosphonate of the general formula (II), wherein: Res represents any polymer support (resin) with or without a linker, Prot represents any NH- protective group, R represents alkyl or alkyloxyalkyl groups.
通用结构(I)的任何化合物的制备;其中:R1和R2是主文中描述的取代基。Cycl-是由式(a)和(b)中的任一表示的基团;其中:R3至R8,X和Y是主文中描述的取代基。上述化合物可用于治疗癌症。制备方法包括将磷酰基甘氨酸的胺基与氨基酸的羧基偶联,然后将上述形成的化合物与甲酰-Cycl衍生物偶联,去保护氨基酸并在温和碱性条件下形成脱氢二酮二肽,该方法可用于制备与通用结构(II)的上述化合物相关的个别衍生物或衍生物库,使用通用结构(II)的固相磷酸酯,其中:Res代表任何聚合物支持(树脂),带有或不带有连接物,Prot代表任何NH-保护基团,R代表烷基或烷氧基烷基基团。
