An alternative, more convenient preparation of intermediate (XXXVIII) from (XXIX) was also reported. Activation of alcohol (XXIX) as the triflate (XXXIX) by means of trifluoromethanesulfonic anhydride, followed by condensation with thiophenol, gave the phenyl thioether (XL). This was oxidized to sulfone (XLI) using N-methylmorpholine-N-oxide in the presence of TPAP. The pivaloyl protecting group of (XLI) was reductively cleaved with DIBAL, giving (XLII). The lithium anion generated from sulfone (XLII) in the presence of n-BuLi was then condensed with aldehyde (XXXV) to furnish the carbinol adduct (XLIII).
