  A Facile New Synthesis of Aldehyde Enamines in High Yield and High Purity

  摘要：

  Aldehyde enamines were synthesized in excellent yield and purity by reacting an aldehyde with 2 equivalents of a secondary amine in cyclohexane in the presence of 1.5 equivalents of CaH2. Distilled yields ranged from 65%-92%.

  A new, facile preparation of enamines was achieved via a two-step sequence: (i) the ready formation of an N-(α-aminoalkyl)benzotriazole derivative from equimolar amounts of benzotriazole, an aldehyde, and a secondary amine, (ii) the elimination of benzotriazole from the derivative by sodium hydride in tetrahydrofuran (THF). The method provides enamines in good overall yields based on the quantity of

  The hydroboration of both acyclic and cyclic aldehyde and ketone enamines with such representative mono- and dialkylboranes as thexylborane and dicyclohexylborane, followed by an oxidative workup, yields the corresponding beta-amino alcohols in good to excellent isolated yields. The hydroboration of ketone and aldehyde enamines with the asymmetric hydroboration reagents monoisopinocampheylborane ((d)IpcBH(2)) and diisopinocampheylborane ((d)Ipc(2)BH) was also investigated, (d)Ipc(2)BH is highly effective for the asymmetric hydroboration of acyclic aldehyde enamines, such as 1-(4-morpholino)-3-phenyl-1-propene and 1-(1-pyrrolidino)-1-octene. Oxidation of the intermediate trialkylborane furnishes the corresponding beta-amino alcohols in 50-86% ee. The stereogenic center of the carbinol carbon is consistently enriched in the R-enantiomer when (d)Ipc(2)BH prepared from (+)-alpha-pinene is used as the hydroboration reagent. The enantiomeric excesses of the beta-amino alcohols synthesized in this study were determined by HPLC using a chiral stationary phase. The absolute configurations of some of the beta-amino alcohols synthesized in this study were determined by chiral HPLC comparison with authentic beta-amino alcohols prepared from chiral epoxides of known absolute configuration.
