Cyclization of (sillyloxy)enynes with ClTi(i-PrO)(3) and i-PrMgCl gives cyclic siloxanes. This cyclization offers a new approach to mixed polyacetate-polypropionate polyketides, and has been applied to the synthesis of the C9-C19 subunit of dictyostatin-1. (C) 2004 Elsevier Ltd. All rights reserved.
