  Chemoenzymatic synthesis of rhodiooctanoside isolated from Chinese medicines, rhodiolae radix

  摘要：

  Direct beta-glucosidation between 1,8-octanediol 5 and D-glucose 6 using the immobilized beta-glucosidase (EC 3.2.1.21) from almonds with the synthetic prepolymer ENTP-4000 gave mono-beta-glucoside 3 in 58% yield, which was converted into n-octyl beta-D-glucopyranoside 2 by means of a chemoenzymatic method. The coupling of n-octyl beta-D-glucopyranoside congener 15 and 2,3,4-tri-O-acetyl-alpha-L-arabinopyranosyl bromide 17, followed by deprotection afforded the synthetic rhodiooctanoside 1, which was identical with natural 1 with respect to the spectral data and specific rotation.
