TextSentencer_T2 |
81-236 |
Sentence |
denotes |
O-aminopropyl starch was prepared by Michael addition of acrylonitrile and subsequent reduction with freshly prepared cobalt boride and sodium borohydride. |

237-374 |
Sentence |
denotes |
In a second approach, the aminopropyl group was introduced via Williamson etherification with N-phthalyl-protected 3-bromo-1-propylamine. |

475-589 |
Sentence |
denotes |
The DS of all samples and the degree of reduction of the cyanoethyl groups were estimated from the 1H NMR spectra. |

TextSentencer_T7 |
705-939 |
Sentence |
denotes |
While the regioselectivity in the thermodynamically controlled reaction was O-6 > O-2 > O-3 (50:37:13), the kinetically controlled process showed strongly preferred O-2-etherification (up to 94%) followed by O-6- and O-3-substitution. |
