Looking for a base cleavable protecting group
« on: March 12, 2013, 09:19:19 AM »
Hey people,

I am looking for a base cleavable protecting group that fulfill the following features:

1. Cleavable under NaOH but not under nucleophilic bases (piperidine or DIPEA)
2. Stable under TFA.
3. Easy to remove. No long reaction times.

I was thinking in TFA as a protecting group, but I think that it is really hard to removed and u need long reaction times.

Any suggestion?
