K-10 effectively catalyzed the condensation and substitution reactions. The approach was based on the direct cyclization of phthalaldehydicacid and opianic acid with substituted hydrazines. The reactions provided excellent yields and high selectivities in very short time (5-35 minutes). phthalazinones - phthalaldehydicacid - opianic acid - hydrazines - montmorillonite K-10 - microwave heating

A catalyst bound α-aminoalkyl radicalintermediate from iminium is developed to control its formation and reactivity with aerobic oxygen. The influence of the catalyst was demonstrated via the ease of radicalintermediate formation and its subsequent reactivity, including the first catalyst-controlled enantioselective aerobic oxidation with a chiral phosphite catalyst.
