Hetero Diels-Alder reaction of olefin with o-quinone methides generated using (±)-binolphosphoric acid for the stereoselective synthesis of 2,4-diarylbenzopyrans: application to the formal synthesis of myristinin B/C

Hetero Diels-Alder reaction of olefin with o-quinone methides (o-QMs) generated using (+/-)-binolphosphoric acid was developed for the stereoselective synthesis of 2,4-diarylbenzopyrans. The method thus developed was utilized in the formal synthesis of myristinin B/C.
