P. Chattopadhyay et al., A SIMPLE CONSTRUCTION OF CHIRAL FUSED BENZOXOCINE RING ETHERS FROM D-GLUCOSE BY REGIOSELECTIVE 8-ENDO-ARYL RADICAL CYCLIZATION, Chemical communications, (22), 1997, pp. 2139-2140
A regioselective 8-endo-trig aryl radical cyclisation of the 5,6-deoxy
-D-xylo-5-enofuranosides 3a and 3b with trin-butyltin hydride provides
the chiral furo[3,2-c][2]benzoxocines 4a and 4b in good yields; the c
rystal structure of 4a is reported.
