SYNTHESIS AND X-RAY CRYSTALLOGRAPHY OF CHIRAL TROPOCORONANDS

Abstract

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