Suzuki-Miyaura coupling on the three upper rims of hexahomotrioxacalix[3]arenes

The efficient functionalization of three upper rims based on Suzuki-Miyaura coupling to temporarily lower rim-protected hexahomotrioxacalix[3]arenes was developed. After deprotection of the three protecting groups, the three upper rim-functionalized and l

7,15,23-Triphenyl-25,26,27-triethylester-2,3,10,11,18,19-hexahomo-3,9,11-trioxacalixarene in a Partial-Cone Conformation

Reaction of p-phenylhexahomocalixarene (I-H) with bromomethyl acetate and potassium carbonate in acetone leads to the title triester derivative, (I-CH2CO2Et) 5,9.113,17>heptacosa-1(25),5,7,9(27),13,15,17(26),21,23-nonaene-25,26,27-triyltris(oxyacetate), C54H54O12>, in a partial-cone conformation, which crystallizes with two molecules in the asymmetric unit.In this conformation, (I-CH2CO2Et) is adapted for selective complexaation of the K+ cation.We describe in this paper the synthesis and conformational behaviour of (I-CH2CO2Et) as determined by 1H NMR spectroscopy and X-ray diffractometry.
