The synthesis of U-71,184 (2), a highly potent analog of the novel antitumor antibiotic CC-1065, is described, the penultimate step of which involves the unmasking of a -hydroxy phenethyl mesylate, which undergoes facile intramolecular elimination to afford the reactive cyclopropylspirocyclohexadienone. Its enantiomer, U-71,185, was also prepared and shown to be biologically inactive.
