Disclosed are methods for preparing 2-alkynyladenosine derivatives of formula A:
or a stereoisomer, pharmaceutically acceptable salt, hydrate, solvate, acid salt hydrate or isomorphic crystalline form thereof, the method comprising the step of:
contacting 2-iodoadenosine-5′-N-ethyluronamide with a compound of formula B:
wherein Z is —C(═O)OR or —CH
2
C(═O)R, where R is a C
1
to C
5
alkyl, preferably
The methods are useful for preparing 2-alkynyladenosine derivatives that are, in certain embodiments, adenosine receptor agonists.
本发明公开了制备式A的2-炔基腺苷衍生物的方法:
其中A可以是立体异构体,药学上可接受的盐、水合物、溶剂合物、酸盐水合物或同晶形式。该方法包括以下步骤:将2-碘腺苷-5'-N-乙基脲与式B的化合物接触:
其中Z是- C(═O)OR或- CH2C(═O)R,其中R是C1到C5的烷基,最好的是。
该方法对于制备2-炔基腺苷衍生物非常有用,某些情况下,这些衍生物是腺苷受体激动剂。
