Acceleration of Catalytic Asymmetric Silylation of Syn-Diols and Triols by Use of a Tetrazole Co-Catalyst

Thesis advisor: Kian L. Tan / The acceleration of catalytic asymmetric silylation of syn-diols and triols by use of an azole additive has been developed. By simply adding 7.5-20 mol % of a commercially available small-molecule, 5-ethylthiotetrazole, to a previously reported chiral catalyst, reactions proceed within one hour delivering the desired products with similarly high yields and enantiomeric ratios; there is minimal reaction during the same period when one of the co-catalysts is absent. In an attempt to better understand this silylation mechanism, computational catalyst design and synthetic development were employed. / Thesis (MS) — Boston College, 2013. / Submitted to: Boston College.
