An Efficient Synthesis of a Dual PPAR α/γ Agonist and the Formation of a Sterically Congested α-Aryloxyisobutyric Acid via a Bargellini Reaction

A practical synthesis of benzisoxazole 1 and its conversion to α-aryloxyisobutyric acid 2 using 1,1,1-trichloro-2-methyl-2-propanol (chloretone) was developed. Benzisoxazole 1 was formed in high yields by the action of either methanesulfonyl chloride/base upon intermediate oxime 8 or with thionyl ch...
