A fast and efficient palladium‐catalyzed fourfolddomino Sonogashira/double‐carbopalladation/CH‐activation reaction that converts simple aromatic systems into complex polycyclic hydrocarbons has been developed. A number of substituted products has thus been prepared in yields up to 89 %. The structural assignment has been confirmed by using single‐crystal X‐ray crystallography. The products show intriguing
一种快速和有效的钯催化的四倍多米诺的Sonogashira /双carbopalladation / C H-活化反应,其将简单芳族体系成复杂的多环烃已经研制成功。因此已经制备了许多取代的产物,产率高达89%。通过使用单晶X射线晶体学已确认了结构分配。该产品显示出令人着迷的荧光活性,因此可以用作化学传感器或荧光成像染料。

A highly efficient palladium‐catalyzed fourfold tandem‐domino reaction consisting of two carbopalladation and two CH‐activation steps was developed for the synthesis of two types of tetrasubstitutedalkenes 3 and 6 with intrinsic helical chirality starting from substrates 1 and 4, respectively. A sixfold tandem‐domino reaction was also developed by including a Sonogashira reaction. 20 compounds with
Diaminoalkanes of Formula I have now been found which are orally active and bind to aspartic proteases to inhibit their activity. They are useful in the treatment or amelioration of diseases associated with elevated levels of aspartic protease activity. The invention also relates to a method for the use of the compounds of Formula I in ameliorating or treating aspartic protease related disorders in a subject in need thereof comprising administering to said subject an effective amount of a compound of Formula I.
Disclosed are compounds according to Formula I:
wherein the variables are defined herein. Such compounds are can bind aspartic proteases to inhibit their activity. They are useful in the treatment or amelioration of diseases associated with aspartic protease activity.
Also described herein are methods of antagonizing aspartic protease inhibitors in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a compound according to Formula I.
