Construction of 2,6-trans pyrans via Prins cyclization and its application towards the total synthesis of methyl sarcophytoate by Hu, Xuhong

“…Prins cyclization reaction involving a homoallylic alcohol with aldehyde is one of the most efficient methods to synthesize tetrahydropyran rings. However, due to the strong 1,3-diaxial interaction, the 2,6-cis tetrahydropyran moiety was formed preferably in most cases. …”

Ladder Polyether Synthesis via Epoxide-Opening Cascades Using a Disappearing Directing Group by Simpson, Graham L, Heffron, Timothy P, Merino, Estíbaliz, Jamison, Timothy F

“…The trimethylsilyl group disappears during the course of the cascade, and thus these are the first epoxide ring-opening cascades that afford ladder polyether subunits containing no directing groups at the end of the cascade.…”
