    摘要: A method for preparing 1,2-dihydroquinolines that is more flexible than the Skraup reaction is provided. The method comprises treating an ortho-alkenyl aniline with a ketone in the presence of a Lewis acid. Novel intermediates and products of this method useful as steroid receptor modulators, as well as pharmaceutical compositions and methods of use thereof are also claimed.

    摘要: A method for preparing C(5)-substituted 1,2-dihydro-5H-chromeno[3,4-.function.]quinolines from a lactol precursor is provided. The method comprises converting the lactol to one of a select number of mixed acetal derivatives, and then treating the acetals with a Grignard reagent. The new process provides products in higher yield and greater purity. Novel intermediates of this method are also claimed.
