sesquiterpenes and total syntheses of (+)-dysodensiol F, (+)-10β,14-dihydroxy-allo-aromadendrane, and (−)-dendroside C aglycon starting from a versatile hydroazulene intermediate were accomplished. The key features of these synthesesinvolve late-stage carbene-mediated diastereoselective cyclopropanation, construction of an unusual cis-fused-hydroazulene skeleton via intramolecular Dieckmann condensation

A novel method has been devised for anti-1,3-aminoalcohols through reductive elimination of iodomethyltetrahydropyrans which are in turn derivedfrom a Prins/Ritter reaction sequence. The synthetic versatility of this method has been explored in the total synthesis of piperidine alkaloids and β-amino acids.

The totalsynthesis of (+)-cryptocaryol A was achieved in 20 steps from (R)-glycidol. The key steps were a Prins cyclization/reductivecleavage sequence to construct the C5–C11 polyol fragment, a diastereoselective aldol reaction to control the stereogenic center at C13, and a stereocontrolled reduction to introduce the stereogenic center at C15.
