Diastereoselective synthesis of the C(17)-C(28) fragment (the C-D spiroketal unit) of spongistatin 1 (altohyrtin A) via a kinetically controlled iodo-spiroketalization reaction.

[reaction: see text] A convergent and stereocontrolled synthesis of spiroketal 15 corresponding to the C-D fragment of spongistatin 1 has been accomplished by a sequence utilizing a kinetically controlled intramolecular iodo-spiroketalization of glycal 2,
