Résumé:
This manuscript describes the reductive removal of trityl and benzyl groups from
N-protected indoles, using indium, magnesium, zinc and aluminum processes and new
method for synthesis an N-tert-Butanesulfinylimines.
In the main part: Chapters 1 and 2 we have reported the development of two efficient
processes one for transforming a wide variety of indoles into the corresponding derivatives
indoles in high yield, using a simple and soft protocol, and other to protect indoles which is
our starting materials.
Chapter 3 shows the deprotection of the trityl (triphenylmethyl) and benzyl groups,
from tritylated and benzylated indoles using indium, magnesium, zinc and aluminum powder
to give the corresponding free indoles.
In the second main part: we have described anew method for the synthesis ofN-tertButanesulfinylimines with a moderate yield.
