The N6 and N9 of adenine can selectively react with sugars and 2-furanmethanol.
Adenine copper complexes activate the N9 of adenine and form di-glycated adenine.
Di-ribosylated adenine and kinetin were formed for the first time from adenine.
Reaction of adenine with 2-furanmethanol generated kinetin and its isomer.
Reaction of adenosine with 2-furanmethanol generated kinetin riboside.
