摘要:
A SYNTHETIC PROCESS FOR PRODUCING LAVANDULOL (III) AND LAVANDULYL ACETATE (V) ECONOMICALLY AND IN PURE FORM IS DISCLOSED. THIS IS ACCOMPLISHED BY A NOVEL PROCESS INVOLVING MAKING LAVANULIC ACID (II BY THE REARRANGEMENT OF A NOVEL COMPOUND, 2-METHYL-BUTEN-2-YL-B,B-DIMETHYL ACRYLATE (I). THE LAVANDULIC ACID SO FORMED MAY BE REDUCED TO LAVANDULOL (III) OR LAVANDULAL (IV), CONVERTED INTO A LOWER ALKYL ESTER (V) OR INTO THE NOVEL LAVANDULIC ACID NITRILE (VI). LAVANDULOL (III) MAY BE TRANSFORMED INTO THE NOVEL LAVANULYL B,B-DIMETHYL ACRYLATE (VII).
