概要

• 論文の詳細を見る

• Oxidation of the furan ring in the D-furanoerythrinan 1 with N-bromoacetamide in protic solvents gave the dioxygenated dihydrofurans 4 or 6. Acidic treatment of 4 or 6 caused two kind of reactions depending on the conditions : one is regeneration of a furan with concomitant introduction of an OR group or a double bond in the adjacent ring to give the ring C-functionalized D-furanoerythrinans 5,8,and 9,and the other is the formation of the γ-lactones 7,10,and 11.
