Abstract
Treatment of 2-(3-hydroxy-5-phenylpent-4-yn-1-yl)-2(trimethylsilylmethyl)te trahydrofuran (18) with Co-2(CO)(8) gave the corresponding cobalt complex, which was subsequently exposed to methanesulfonyl chloride and triethylamin e in methylene chloride at refluxing temperature to provide the oxocane der ivative 20 in 72% yield. This method was found to be applicable for constru ction of the oxonane framework. (C) 2000 Elsevier Science Ltd. All rights r eserved.
