A stereoselective synthesis of the C21-C29 fragment of (+)-Sorangicin A has been described following our recently developed iodine-catalyzed tandem isomerization followed by C-O and C-C bond formation for the construction of trans-2,6-disubstituted dihydropyran as the key step. In this Letter, the problem of installing the C25 asymmetric center has been sorted out by utilizing an iodolactonization strategy. (C) 2015 Elsevier Ltd. All rights reserved.
