Facile syntheses of 3',4'-methylenedioxy-2,2-dimethylpyrano- [5'',6'': 7,8] -flavone and (±)-ponganone III, two pyranoflavanoids

Article abstract of DOI:10.1080/00397919908085964

Facile syntheses of two naturally occurring pyranoflavanoids, 3',4'- methylenedioxy-2_,2_-dimethylpyrano-[5_,6'':7,8]-flavone (1) and (±)- ponganone III (2), have been achieved through the key intermediate chromene 6 by a DDQ
