Description: Herein are described optimization studies on the first step of a one-pot, three-component reaction towards biologically active 2,6-disubstituted dihydropyrans (DHPs). Bismuth tribromide proves to be a satisfactory catalyst for a Mukaiyama aldol reaction between an aldehyde or ketone and a silylated enol ether or ketene acetal. This environmentally benign catalyst establishes the viability of a three-component, one-pot reaction toward DHP ring systems, present in anti-cancer, anti-fungal, and anti-osteoporosis agents, among others.
