New camphor-derived sulfur chiral controllers: Synthesis of (2R-exo)-10-methylthio-2-bornanethiol and (2R-exo)-2,10-bis(methylthio)bornane

Article abstract of DOI:10.1016/S0957-4166(96)00463-6

An efficient preparation of two camphor-derived controllers [(2R-exo)-10-methylthio-2-bornanethiol 1b and (2R-exo)-2,10-bis(methylthio)bornane 2] potentially useful as a ligands or chiral auxiliaries in asymmetric synthesis is described. Both compounds ha
