[0034] Example 1
[0035] Synthesis and preparation of 5-{4-[3-(silicaoxydimethylsilyl)propoxy]phenoxy}acenaphthylenequinone bis(2,6-diisopropyl)anilide support e1 The route is as follows:
[0036]
[0037] The specific steps are as follows:
[0038] References for the synthesis of 5-bromoacenaphthoquinone [J Am Chem Soc,2013,135(46):17469], References for the synthesis of 4-allyloxyphenol a1 [J Med Chem,2011,54(13): 4659]
[0039] Synthesis of 5-(4-allyloxyphenoxy)acenaphthylenequinone b1:
[0040] Add 12.7g (48.6mmol) of 5-bromoacenaphthoquinone, 13.8g (100mmol) K to a 100ml reaction flask 2 CO 3 , 33ml dry DMF, start stirring. During the stirring process, 15g (100mmol) of a1 was added and reacted at 60°C. Chromatography chromatography tracked the reaction of the reactants to complete, and the reaction was stopped. Pour the reacted dark brown solution into saturated NaCl solution to become a brown suspension, extract with dichloromethane for 2-3 times, and use anhydrous MgSO for t...
