Four consecutive reactions in one pot: cascade formation of an unprecedented triphosphatricyclo[3.2.1.02,7]oct-3-ene†
Abstract
A hitherto unknown triphosphatricyclo[3.2.1.02,7]oct-3-ene was obtained in high yield by a total of four consecutive pericyclic reactions from di-2-pyrone and excess TMS-CP. DFT calculations gave insight into the reaction mechanism. The chiral phosphorus cage readily forms coordination compounds with Au(I) and Cu(I).
