nitiol has culminated in the construction of two epimeric hydroxylated derivatives, the 1,22-dihydroxynitianes. Key stereodefining steps in the construction of the A-ring fragment (13) were the use of a siloxy−epoxide rearrangement reaction, a Pauson−Khand reaction, a Norrish 1 photochemical cleavage reaction, and a highlyregio- and stereoselective hydrostannylation reaction of an ynoate. The stereochemistry
