Catalytic asymmetric hetero-Diels-Alder route to a key intermediate for the synthesis of calyxin L
A catalytic asymmetric formal synthesis of diarylheptanoid natural product calyxin L has been achieved by incorporating an enantio- and diastereoselective hetero-Diels-Alder (HDA) reaction, a Suzuki-Miyaura coupling, and a stereocontrolled catalytic hydro
