Microwave solvent-free conditions developed for Meyersâ lactamization, a typical bielectrophile-binucleophile reaction that produces quaternary centers in a stereoselective manner, give access to Meyersâ chiral lactams in good yield and high diastereoselectivity in short times.
a mixture of ethanol and water yields the expected lactams, we exemplified the reaction and procedure with the preparation of a library of 80 members. Our synthesis scheme is validated for synthesis scales from 1 to 100 mg. Therefore, it can be used both to produce rapidly test samples for HTS as well as to prepare intermediates for the synthesis of more elaborated nature-inspired compounds.
