Synthesis of chiral trans-fused pyrano[3,2-c][2]benzoxocines from d-mannose by regioselective 8-endo-aryl radical cyclization
摘要:
A simple chiral synthesis of trans-pyrano[3,2-c][2]benzoxocines 8a-d in good yields (60-75%) through regioselective 8-endo-trig aryl radical cyclization of the D-mannose derived enopyranosides 7a-d with Bu3SnH is described. (C) 2002 Elsevier Science Ltd. All rights reserved.
