Application

2,5-Dimethoxybenzyl alcohol was used as starting reagent in the synthesis of [(S)S]-3,6-dimethoxy-2-(p-tolylsulfinyl)-benzaldehyde. It was used in the synthesis of daunornycinone. It was also used in the preparation of pillar[n]arenes (n = 5 or 6) via cyclooligomerization reaction with an appropriate Lewis acid catalyst.
