Abstract

Whereas the protecting-group pattern of SDA 1 was conceived for the construction of linear oligomers through the amino group in the 6-position [12] following Fmoc strategy, SDA 2 can be employed for the synthesis of branched structures since the two amino groups are orthogonally protected with the Fmoc group and as an azide, respectively. We decided to use methoxymethyl (MOM) groups for hydroxy protection, because they are small and ...
