Figure 3: retro-Michael/Michael reaction.
From: Biomimetically inspired asymmetric total synthesis of (+)-19-dehydroxyl arisandilactone A
DBU mediated a biomimetic tandem retro-Michael/Michael reaction for the formation of (11S, 12R)-dihydrostemofoline (C) from (11S, 12S)-dihydrostemofoline (A) through intermediate B.
