• In combination with NaBH 4, induces asymmetric reduction of functionalized ketones with ee figures approaching those achieved with more expensive reagents: J. Chem. Soc. Perkin 1, 1826 (1990).
• Preferred acid catalyst, in combination with MgSO 4, for acetalization of unsaturated aldehydes with ethylene glycol, giving less double bond isomerization than stronger acids including tosic and succinic: J. Org. Chem., 60, 2931 (1995).
• Resolving agent for chiral bases. For improved resolution technique using two immiscible solvents and half equivalent of resolving agent, claimed to give higher optical purities and faster resolutions than conventional methods, see: Tetrahedron, 41, 2465 (1985).
