Nomenclature overkill
Lithium aluminium hydride (3.35 g, 83.9 mmol) was added in one portion to a stirred solution of lactam 44 (3.36 g, 13.3 mmol) in THF (52 cm3) at 0 °C under nitrogen. The resulting suspension was heated at reflux for 16 h. After cooling to 0 °C, Et2O (20 cm3) was added followed by the portionwise addition (CARE) of solid hydrated sodium sulfate until effervescence ceased. The solids were removed by filtration through Celite and the filter cake was washed with 9:1 CH2Cl2-MeOH (150 cm3). The filtrate was dried (Na2SO4) and evaporated under reduced pressure to give the crude product as a brown oil. Purification by Kugelrohr distillation gave diamine (+)-24 (2.27 g, 88%) as a colourless oil, identical spectroscopically to rac-24, bp 110-120 °C/0.5 mmHg.
None of the bees Lego asked has heard about this method before. Perhaps somewhen a bee will try this method.
