  摘要：

  The allyl glycoside beta-D-Glcp-(1 --> 3)-beta-D-Glcp-(1 --> 3)-[beta-D-Glcp-(1 --> 6)]-beta-D-Glcp-(1 --> 3)-beta-D-Glcp-(1 --> 3)-[beta-D-Glcp(1 --> 6)]-alpha-D-Glcp (18) and the acetonyl glycoside of beta-D-Glcp-(1 --> 3)-[beta-D-Glcp-(1 --> 6)]-beta-D-Glcp-(1 --> 3)-beta-D-Glcp-(1 --> 3)-[beta-D-Glcp-(1 --> 6)]-beta-D-Glcp-(1 --> 3)-beta-D-Glcp-(1 --> 3)-[beta-D-Glcp-(1 --> 6)]-alpha-D-Glcp (28) were synthesized as analogues of the lentinan heptaose repeating unit. 4,6-O-Benzylidenated monosaccharide donor 3 and 4,6-0-benzylidenated tetrasaccharide acceptor 14 were used to ensure the P-linkage in the synthesis of 18, while 4,6-0-benzylidenated disaccharide acceptor 20, and 4,6-0-benzylidenated disaccharide donors 21 and 24 were used to ensure the beta-linkage in the synthesis of 28.
