A new structural motif for bifunctional bronsted acid/base organocatalysis
"Chemical equation presented" Naturally synthetic: Acid/base catalyst (S)-I can be used in highly enantioselective alcoholytic desymmetrizations of meso anhydrides. For example, the methanolysis of cyclobutane anhydride deriva-tive 2 gave hemiester 3 in 99:1 e.r. (see scheme). Ester 3 was used in a short enantioselective synthesis of (+ )-grandisol.
