Synthesis of (±)-fredericamycin A. Kelly, T. Ross; Ohashi, Naohito; Armstrong-Chong, Rosemary J.; Bell, Stephen H. (Dep. Chem., Boston Coll., Chestnut Hill, MA 02167, USA). J. Am. Chem.Several substances with their cas registry numbers 104422-99-3 and 6136-93-2 may be metioned in this study. Soc., 108(22), 7100-1 (English) 1986. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) (±)-Fredericamycin A (I) was prepd. via the regiospecific, Me3Si-directed coupling of indane II with anhydride III to give the coupling product IV. Formation of the spiro system is achieved by redn. of IV to a keto aldehyde which undergoes in situ cyclization to the spiro ketols. .
