  2. 21. Acetals - Exploring reactivity for improved carbohydrate synthesis

    Author : Markus Ohlin; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In my research, I have explored various aspects of acetals and their reactivity. Acetals have a central role in carbohydrate chemistry as an inherent functionality and as versatile protecting groups. The first part of the thesis summarizes results on regioselective reductive openings of benzylidene acetals. READ MORE
