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.
描述了新型抗肿瘤抗生素CC-1065的高效类似物U-71,184(2)的合成,其倒数第二步涉及对甲氧基苯甲酸羟乙酯的解掩蔽,后者经过分子内容易的消除以提供反应性环丙基螺环己二酮。还制备了其对映异构体U-71,185,并显示其对生物无活性。
