The synthesis of several chiral tropocoronands (6 and 7) has been accomplis
hed. These compounds have been shown to complex with various metals. Tropoc
oronands that have been synthesized include H-2(TC-3,cyhex) through H2(TC-G
,cyhex) (6) and H-2(TC-3,diphen) through H-2(TC-6,diphen) (7). The route is
short and the tropocoronands are easily purified by chromatography or recr
ystallization. Two other groups have been incorporated into tropocoronands,
H-2(TC-3,binap) (9) and H-2(TC-6,pent) (10).
