This terminology may be a little confusing because we also use the terms stripping and fractionation when we discuss processing sequence options in distillation. This confusion results from historical use of the terms and you just need to keep the context in mind when reading or discussing the material. With a little practice you will find that the reason for using the same terms is that many of the systems called stripping or fractionation systems have the same characteristics regardless of using a processing sequence or heat flow analysis of the unit.

To a stirred solution of glyoxylic acid monohydrate (92 mg, 1 mmol) in CH 2 Cl 2 (7 mL) was added benzhydrylamine (183 mg, 1 mmol), followed by phenylboronic acid (122 mg, 1 mmol). After the flask was purged with argon and sealed, the reaction mixture was stirred vigorously at rt for 48 h. The resulting precipitate was isolated by filtration, washed with CH 2 Cl 2 (10 mL), and purified by ion-exchange chromatography (Dowex 50W-X8) to afford the title compound (266 mg, 84%): 1 H NMR (360 MHz, DMSO- d 6 ) δ – (m, 15H), (s, 1H), (s, 1H); 13 C NMR (90 MHz, DMSO- d 6 ) δ , , , , , , , , , , .
