The vanadium(V)-catalyzed asymmetric epoxidation of primary allylic alcohols by the optically active TADDOL-derived hydroperoxide as the asymmetric controller provides the corresponding (R)-epoxides in up to 72% ee. From this mechanistic study we conclude

The chloro alcohols 4-6 derived from TADDOLs (=α,α, α′,α′-tetraaryl-1,3-dioxolan-4,5-dimethanols) are used to prepare corresponding sulfanyl alcohols, ethers, and amines (Scheme 1 and Table 1). The dithiol analog of TADDOL and derivatives thereof, 45-49,

As a part of our research program aimed at the synthesis of TADDOL-derived ligands with heteroatoms other than oxygen as chelating units, we describe here new or improved routes to amino TADDOL-analogs (4, 5, 17-19, 21, 22, 26, 34 and 35) and thio-TADDOL-analogs (27-30 and 32).The sulfinato-thiolato Pt-complex 44 was prepared by an oxidative insertion of Pt into the S-S-bond of the corresponding thiosulfinate 29.Furthermore, the X-ray crystal structures of some of the new compounds (2-5, 28, 29, 32, 42 and 44) are presented and discussed. - Keywords: TADDOL derivative; chiral ligand; X-ray structure; platinum complex
