stereostructures even by the current highly advanced spectroscopic methods, especially in acyclic systems including quaternary carbon centers such as C10-C11, C14-C15, and C18-C19 in 1. In this paper, we report that the total assignment of the incomplete stereostructure of (+)-aurilol (1) to the structural formula 2 has been accomplished through its first asymmetric total synthesis featuring the highly regio- and
