Technical Description
This invention relates to an organocatalyst-promoted process for preparing trisubstituted 1H-Pyrrole-3-carbaldehyde compounds of Formula III via a formal domino 1,3-dipolar cycloaddition/ring-opening/ring-cleavage reaction pathway. Using easily accessible alpha, beta-unsaturated aldehydes and substituted 4-methylthiazolium salts, the metal-free method operates at room temperature to streamline active pharmaceutical ingredient (API) synthesis.
