    摘要: A process for preparing (meth)acrylic esters (F) of alcohols (A) having at least one epoxy group, in which at least one alcohol (A) having at least one epoxy group is esterified with (meth)acrylic acid (S) or is transesterified with at least one (meth)acrylic ester (D) in the presence of at least one enzyme, the alcoholic leaving group being stable under the reaction conditions in the case of the transesterification.

    摘要: The present invention relates to a method for producing 1-hydroxymethyl-1,2-diphenyloxiranes from 2,3-diphenylpropenals by means of epoxidation and reduction. The formation of objectionable by-products can be suppressed in that the reduction is started before the 2,3-5 diphenylpropenal is completely converted. The hydroxymethyl diphenyloxiranes represent valuable intermediate products for producing 1-azolylmethyl-1,2-diphenyloxiranes, wherein the latter can be easily produced from said intermediate products by introducing the azolyl group.
