Abstract
The influence of a pressure of 60 MPa on theconversion and the stereoselectivity of the Diels-Alderreaction of 2- and 3-furylmethanol with methyl-, benzyl-, andphenylmaleimide was studied in a capillary micro-reactor. Inthe case of 2-furylmethanol, a 1.7-fold higher conversion wasobtained at 60 MPa with respect to 0.1 MPa experiments.Pressure positively affects the formation of the exo isomer,whereas in the case of 3-furylmethanol pressure does notaffect the reaction.
