The development of a robust process to 6,6-dimethyl-3-oxabicyclo[3.1.0]hexan-2-one, a key intermediate toward several active compounds of interest, is described. A scalable organocatalyzed desymmetrization was first studied and the reaction proved to be compatible with standard dilution. A kinetic study was performed to elucidate substrate and catalyst concentration dependences. Next, a chemoselective reduction of the carboxylic acid was developed. The scalability was demonstrated on 100 g scale through a fully telescoped process.
