DOI: 10.1016/j.carbpol.2017.10.046
Abstract: Two kinds of regioselectively substituted curdlan hetero ester, 2,4-di-O-acetyl-6-O-propionyl-curdlan (CD24Ac6Pr) and 2,4-di-O-propionyl-6-O-acetyl-curdlan (CD24Pr6Ac), were synthesized. By repeating detritylation and esterification, a new method to remove trityl group from 6-O-trityl-curdlan without acyl migration was developed. Their… read more here.
