Deoxygenative Divergent Synthesis: En Route to Quinic Acid Chirons [PDF]

open access: yesOrganic Letters, 2020
The installation of vicinal mesylate and silyl ether groups in a quinic acid derivative generates a system prone for stereoselective borane-catalyzed hydrosilylation through a siloxonium intermediate. The diversification of the reaction conditions allowed the construction of different defunctionalized fragments foreseen as useful synthetic fragments ...
