This application provides for compounds of the formula Formula I or a pharmaceutically acceptable salt thereof, wherein the individual variables are defined herein, as well as processes to prepare these compounds, pharmaceutical compositions comprising the same and their use in treating disease state associated with the CRTH2 receptor.
mild conditions, and the reaction of substituted benzoxazoles, oxazole and benzothiazole occurred even at room temperature. The substrate scope of the reaction was turned out to include mono-, di- and trisubstituted alkenyl bromides. To validate the scalability of this method, 5-Methyl-2-(prop-1-en-2-yl)benzoxazole (3c) was prepared on one-gram scale at room temperature.
The N-heterocycliccarbene (NHC)-catalyzed dimerizations of a variety of disubstituted Michael acceptors have been investigated. In addition to the tail-to-tail dimerization of methacrylates reported previously, the scope of vinylidene substrates expands to γ-methyl-α-methylene-γ-butyrolactone, dimethyl 2-methylenepentanedioate, dimethyl itaconate, methacrylamides, and 2-isopropenylbenzoxazole, none
