Ru/C catalyzed cyclization of linear α,ω-diamines to cyclic amines in water
摘要:
A facile and convenient way to prepare cyclic amines in water was achieved by the catalyst system composed of Ru/C and Al powder The alpha,omega-diaminoalkanes, 1.4-diaminobutane, 1,5-diaminopentane. and 1.6-diamino-heptane were converted to corresponding cyclic amines in good yields The Use Of D2O provided a novel route to obtain deuterated cyclic amines in good yields (C) 2009 Elsevier Ltd All rights reserved
