Radical spirocyclization: synthesis of an appropriately oxygenated spiro compound related to the antitumor antibiotic fredericamycin A: Radical spirocyclization: synthesis of an appropriately oxygenated spiro compound related to the antitumor antibiotic fredericamycin A. Clive, Derrick, L. J.; Angoh, A. 107135-53-5 and 4009-98-7 are also occured in this study. Gaetan; Bennett, Sharon M. (Dep. Chem., Univ. Alberta, Edmonton, AB T6G 2G2, Can.). J. Org. Chem., 52(7), 1339-42 (English) 1987. CODEN: JOCEAH. ISSN: 0022-3263. DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) The spiro compd. I, that represents the central 4 rings of the antitumor agent, fredericamycin A, has been synthesized by using the general technique of radical spirocyclization. The key intermediate II was assembled from 7-methoxyindancarboxaldehyde and 2,3,6-Br(MeO)2C6H2CYCPh, followed by oxidn. of the resulting alc. Phenylselenylation of II and treatment with Ph3SnH gave the spirocycle which on ozonolysis and deprotection with BBr3 gave I. .
