Trisamine resin

In order to explore the potential of CHD resins as scavenger materials, 1-ethyl-3,5-dimethoxycydohexa-2,5-dienecarboxylic acid was anchored to a commercially available trisamine resin (Scheme 7.106), which yielded a high-loading cyclohexane-1,3-dione scavenger resin (CHD-SR) [125]. [Pg.369]

Scheme 2.57 Three component condensation reaction using polymer supported scavenger purification alternatively the trisamine resin could be substituted for purification in this step.

A library of dihydroxytetrahydrofurans was readily prepared from isosorbide." Epoxide 73 was produced in two steps from isosorbide (72)."" Subsequently, 73 was heated with secondary amines 68 to afford the corresponding amino alcohols 74 (Scheme 7.15). PS-lsocyanate resin was used to remove excess secondary amine 68. Treatment of alcohols 74 with isocyanates 75 gave the desired carbamates " PS-Trisamine resin removed excess isocyanate. Aqueous, acid-promoted hydrolysis of acetonides gave diols 76. [Pg.176]
