A. Dondoni et al., THE ASSEMBLY OF CARBON-LINKED CALIXARENE-CARBOHYDRATE STRUCTURES (C-CALIXSUGARS) BY MULTIPLE WITTIG OLEFINATION, Tetrahedron letters, 38(44), 1997, pp. 7801-7804
The Wittig olefination of the O-propyl tetraformylcalix[4]arene 1 with
sugar phosphoranes and reduction of the resulting alkenes lead to cal
ixarene derivatives holding three and four carbohydrate units through
an ethylene linkage (C-calixsugars). (C) 1997 Elsevier Science Ltd.
