Prins cyclization is one of the most convergent strategies for the synthesis of 2,6-disubstituted tetrahydropyran rings from homoallylic alcohols and aldehydes. However, several limitations, such as the possibility of racemization of the homoallylic alcohol and substrate compatibility, have rendered this methodology a less preferred choice in the total synthesis of natural products containing the THP motifs. The emphasis of this thesis is placed on the evolution of a novel catalytic Prins cyclization to overcome these current limitations, and manifestation of its applicability to the enantioselective synthesis of natural products.
