A concise (9-step) synthesis of the tropoloisoquinoline alkaloid pareitropone has been achieved starting from 2-bromoisovanillin. The key step features oxidative cyclization of a readily available… Expand
Boron-Catalyzed Site-Selective Reduction of Carbohydrate Derivatives with Catecholborane
- J. Lowe, Youngran Seo, M. Gagné
- Chemistry
- 24 July 2018
Catalytic sp3 C–O bond cleavage using B(C6F5)3/HBcat is reported. This method is first demonstrated on simple ethers and silyl protected alcohols, which exhibit reactivity parallel to the known… Expand
Positional Selectivity in the Hydrosilylative Partial Deoxygenation of Disaccharides by Boron Catalysts
- Youngran Seo, M. Gagné
- Chemistry
- 5 January 2018
The catalytic partial deoxygenation of the per-silylated gluco-disaccharides maltose, cellobiose, trehalose, and isomaltose by Me2EtSiH and the Lewis acid catalyst B(C6F5)3 have been examined to… Expand
Controlling Sugar Deoxygenation Products from Biomass by Choice of Fluoroarylborane Catalyst
- Youngran Seo, J. Lowe, M. Gagné
- Chemistry
- 13 June 2019
The feedstocks from biomass are defined and limited by nature, but through the choice of catalyst, one may change the deoxygenation outcome. We report divergent but selective deoxygenation of sugars… Expand
N-Hydroxymethyl derivatives of α-amino aldehydes used for the stereoselective syntheses of β-amino-α-hydroxy acids
