A set of B(C6F5)3-catalyzed methods for diversification of unsaturated carbohydrate derived substrates is disclosed. Lewis acid cyclization, allylic alcohol hydrosilylation, and selective silyl group exchange is achieved with this single versatile catalyst. Allylic polyols and highly enriched (Z)-triols are obtained in high yields under a single-step protocol.
