ABSTRAK
Sintesis dan uji aktivitas antioksidan senyawa 2-metoksi-4,6-di(prop-1-enil) fenol dari eugenol telah diteliti. Sintesis dilakukan melalui tiga tahap reaksi. Tahap pertama dilakukan reaksi O-alilasi terkatalisis misel CTAB terhadap eugenol pada suhu ruangan diperoleh 4-alil-1-(aliloksi)-2-metoksibenzena (2). Senyawa (2) selanjutnya dipanaskan dengan mengalami penataan ulang Claisen dan diperoleh 2,4-dialil-6-metoksifenol (3). Tahap akhir dilakukan isomerisasi dalam kondisi basa dalam pelarut etilen glikol terhadap senyawa (3)diperoleh 2
