3-indenyllithium leads to fredericamycin A core compound 5, whereas condensation of methylenedioxyphthalide 7b or 8 with lithiated N-methyltetrahydroisoquinoline–BF3 complex 9 affords spirobenzylisoquinolinealkaloids raddeanine 12, corydaine 13 and yenhusomidine 13.
Efficient photochemical transformation of spiro[4.n]-2,5-diones to γ-alkylidene γ-butyrolactones: its relevance to photostability of Fredericamycin A

DOI:10.1039/c39930000870
日期:——
Irradiation of a variety of model spirodiones related to the antitumour antibiotic Fredericamycin A in various solvents at 300 nm furnishes quantitative yields of γ-alkylidene γ-butyrolactones; its relevance to the typical shape alteration, photostability and consequent biological response of Fredericamycin is discussed.
