The ortho ester Claisen rearrangement of trisubstituted allylicalcohols exhibits significant levels of diastereoselection. In E allylicalcohols, a 1,3-diaxial interaction develops in the chairlike transition state leading to the anti isomer, rendering the reaction syn selective by a factor of 3-5 to 1. In Zallylicalcohols, the 1,3-diaxial interaction develops in the transition state leading to

The present invention relates to biaryl derivatives of Formula 1, a method for preparing the same, a pharmaceutical composition comprising the same and use thereof. The biaryl derivatives of Formula 1 according to the present invention promote GLP-1 formation in the gastrointestinal tract and improve insulin resistance in the liver or in muscle due to anti-inflammatory action in macrophages, lipocytes, etc., and can accordingly be effectively used for preventing or treating diabetes, complications of diabetes, obesity, non-alcoholic fatty liver, steatohepatitis, osteoporosis or inflammation.
