Abstract
The C(18-28) CD-ring spiroketal subunit of the spongistatins, marine p olyether macrolides with unprecedented antitumor activity, has been ge nerated via a highly convergent and completely stereocontrolled sequen ce. Key operations include a one-flask dithiane bisalkylation and a me tal-assisted spiroketal equilibration. (C) 1997 Elsevier Science Ltd.
