摘要：

(Chemical Equation Presented) Weigh it out in air! The DABAL reagent (Me3Al)2·(DABCO) (DABCO = 1,4-diazabicyclo[2.2.2] octane) can be easily handled under normal laboratory conditions. Furthermore, chiral secondary alcohols can be efficiently prepared from prochiral aldehydes (see scheme; TOF = turnover frequency) by using either DABAL or AIR3 reagents (R = Me, Et). Thus, DABAL can be used as an efficient, convenient alternative to the Schumann-Blum reagent. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
