Dear list members,
I am currently looking for a method to mono protect ethane-1,2-diamine
(ethalenediamine). I wish to use the protected diamine in a double
condensation reaction with a phenol, thus producing a six membered ring
incorporating the 1,2 positions of the benzene ring.
C1-O-CH2-N(CH2CH2NHP)CH2-C2.
I believe the ether link will be susceptible to acidic
deprotection,resulting in the reformation of the phenol.
I an also considering the same reaction method with a hydroxyamine
(ethanolamine etc) as such a protecting group that is also selective for
primary alcohols over amines would be ideal.
I have in mind Fmoc, as it can be removed under mild conditions, but I
would be grateful for any input from somebody with experimental experience
in this area.
Kindly yours
CW
