DMAP Promoted Tandem Addition Reactions Forming Substituted Tetrahydroxanthones
摘要:
Substituted tetrahydroxanthones are constructed using a DMAP-promoted tandem nucleophilic addition process. The reaction yields range from 39% to 73%. Disubstituted tetrahydroxanthones are generated as a similar to 2.3:1 mixture of diastereomers favoring the formation of the trans-isomer.
