The present invention relates to a process for linking two molecules by means of a Diels Alder reaction with inverse electron requirement (DARinv), comprising the following steps: reaction of a (a) triazine or tetrazine with one or more electron-attracting substituents on the ring as a diene component, the electron-attracting substituents being selected from:
COOR
C(O)NR
2
CX
3
(X=halogen)
halogen
CN
SO
2
—R or SO
3
—R
PR
2
wherein R═H, alkyl, aryl, heterocycle, which in turn may be substituted, where appropriate, with alkyl, OH, SH, halogen, aryl, heterocycle, nitro, carboxyamido or amine group. —heterocyclic rings having 1, 2 or 3 N, O or S atoms with a ring size of 5 or 6 ring members, which are substituted with at least one carboxyl, sulfonic acid or phosphone group with (b) an isolated double bond or triple bond in a (hetero)carbocyclic ring or an isolated olefinic double bond or triple bond in a linear or branched hydrocarbon chain which may also contain heteroatoms, where appropriate, as a dienophile component.
本发明涉及一种利用逆电子需求的Diels-Alder反应(DARinv)将两种分子通过连接的方法,包括以下步骤:将(a)三嗪或四嗪与环上的一个或多个吸电子取代基反应作为二烯组分,所述吸电子取代基被选择自:COOR、C(O)NR2、CX3(X=卤)、卤、CNSO2—R或SO3—RPR2,其中R=H、烷基、芳基、杂环,后者可能被适当地取代,如有必要,可用烷基、OH、SH、卤、芳基、杂环、硝基、羧基氨基或胺基团取代;(b)一种孤立的双键或三键存在于(杂)碳环上,或者一种孤立的烯烃双键或三键存在于线性或支链烃链中,该链也可能含有杂原子,如有必要,作为二烯酰组分。
