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-phenol rearrangement reaction. A decisive effect of MgBr2 in the reaction of Grignard reagents is also described.
通过使用该碱,已开发出一种有效的替代方法,可替代4,6-二叔丁基-2,2-二戊基-2,3-二氢-5-苯并呋喃醇( BO-653)。 -促进的二烯酮-苯酚重排反应。还描述了MgBr 2在格氏试剂反应中的决定性作用。
