✦ Synopsis

3,

Part of the projected Ph. D. thesis of P.B.R., and of the Master's thesis of H . S., ETH-Zurich, 1997. For short review articles, see [l]. Besides a distyryl-TADDOL [2], a distyryl salen has been used as a cross-linker in a polymerization [4]. There are, of course, myriades of chiral ligands which were polymer hound or copolymerized for immobilization, see ref. in [2], and two recent articles on soluble [5] and insoluble polymers containing quinine-type ligands for dihydroxylations.
