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.

Abstractmagnified imageA stereoselective total synthesis of (+)‐cryptocarya diacetate (1) was achieved by two different routes (Schemes 2 and 3). The sequences involve LiAlH4/LiI reduction, ring‐closing metathesis, Prins cyclization, Wacker oxidation, and Wittig olefination reactions as key steps.
