Linear polyaldehydes and polyalkenes derived from starch
Abstract
Amylose (I) has been converted by photolysis of its 6-azido-6-deoxy-derivative (III) into a 6-aldehydo-analogue (IV) of amylose, and the 2,3-di-O-p-tolylsulphonly-6-O-trityl derivative (VII) of (I) has been converted into a 2,3-unsaturated polymer (VIII); the products (IV) and (VIII) may be useful for enzymic studies and as precursors for novel polyfunctional and crosslinked polymers.
