The ketone 3 has been resolved using various enzyme-catalysed reactions and the enantiomer (+)-3 was transformed into the benzoate 8 while (–)-3 was converted into the esters 10 and 11; compounds 8 and 10 are complementary sections of leukotriene B4 while compounds 8 and 11 are late-stage synthons for leukotriene B3.
酮3已通过各种酶催化反应拆分,对映体(+)- 3转化为
苯甲酸酯8,而(-)- 3转化为酯10和11;化合物8和10是
白三烯B 4的互补部分,而化合物8和11是
白三烯B 3的后期合成子。
