An efficient alternative route to 4,6-di-tert-butyl-2,2-dipentyl-2,3-dihydro-5-benzofuranol (BO-653), a potent antiatherogenic antioxidant, has been developed by the application of the base-promoted dienone-phenolrearrangement reaction. A decisive effect of MgBr2 in the reaction of Grignard reagents is also described.
