2-Propenoic acid, 1,7,7-trimethylbicyclo[2.2.1]hept-2-yl ester, (1S-exo)- (9CI) synthesis

Yield:136374-53-3 92.8%

Reaction Conditions:

with 10H-phenothiazine for 0.5 h;UV-irradiation;Reagent/catalyst;

Steps:

2; 4; 6 Example 6

Add 136g camphene (1mol) into 36g acrylic acid (0.5mol), dissolve it, stir well, add 8.95g (5%) catalyst solid strong acid resin Amberlyst 15 and 0.18g (0.5%) polymerization inhibitor phenothiazine, stir well , Placed under a 300W UV light source, and reacted while stirring at a rotation speed of 300r/min. The reaction was stopped after 30 minutes, and then the pure and transparent isobornyl acrylate was obtained by rotary evaporation under reduced pressure. The measured yield was 92.8%.
