11synthesis methods
Synthesized by immobilized lipase-catalyzed alcoholysis and esterification in organic solvents.
-

Yield:628-97-7 97%

Reaction Conditions:

with alumina methanesulfonic acid at 120; for 0.333333 h;Microwave irradiation;

Steps:

Representative Procedure for Preparation of Aromatic and Aliphatic Esters (Table 1)

General procedure: In a typical reaction, AMA 2:3 (332 g, 0.6 mol), the corresponding carboxylicacid (1 mol), and alcohol (1.5-2 mol) were mixed in the provided reaction glass tubeequipped with a screw cap and magnetic agitation until a wet mixture was achieved.The reaction mixture was irradiated with microwaves (Anton Parr Monowave 300reactor) at 80 C for 8 min or 120 C for 20 min. On cooling, the mixture was diluted with dichloromethane (41 mL), filtered under gravity, and washed with dichloromethane;then the filtrate was washed with Na2CO3 (ss) and water. The organic layerwas dried over Na2SO4, filtered, and concentrated under reduced pressure to give theester.
