, p. 2913 - 2919 (2001)
The improved synthesis of Jacobsen catalyst 1 was developed. For both enantiomers the obtained overall yield starting from commercially available 4 was 80-85%.
3,5-Di-(tert-Butyl)-6-fluoro-cycloSal-d4TMP - A Pronucleotide with a Considerably Improved Masking Group
Ducho, Christian,Wendicke, Silke,Goerbig, Ulf,Balzarini, Jan,Meier, Chris
, p. 4786 - 4791 (2003)
A new, considerably improved cycloSal masking group has been developed. This new group combines four desirable properties and has been attached to the anti-HIV drug 2′,3′-dideoxy-2′,3′-didehydrothymidine (d4T, 1) to give 3,5-(di-tert-butyl)-6-fluoro-cycloSal-d4TMP (2i). This phosphate triester has a reasonable chemical half-life, highly selectively released d4TMP, has poor - if any - inhibitory effect on butyrylcholinesterase (BChE), and achieved the TK-bypass.

PNO ligand containing planar chiral ferrocene and application thereof

Paragraph 0114-0118, (2021/06/21)
The invention discloses a PNO ligand containing planar chiral ferrocene and application thereof. The PNO ligand containing planar chiral ferrocene is a planar chiral ferrocene-containing and phenol-containing PNO ligand as shown in a general formula (I) or (II) which is described in the specification, or a planar chiral ferrocene-containing and aryl-phosphoric-acid-containingPNO ligand containing as shown in a general formula (III) or (IV) which is described in the specification, or a planar chiral ferrocene-containing and carbon-chiral-phenol-containingPNO ligand as shown in a general formula (V) or (VI) which is described in the specification. The invention provides tridentate PNO ligands and processes for their complexation with transition metal salts or transition metal complexes; the introduction of salicylaldehyde and derivatives thereof, which are simple and easy to obtain, enables the ligands to have a bifunctionalization effect, and -OH in a formed catalyst has stronger acidity and is beneficial to combination with N/O in polar double bonds. Therefore, due to the bifunctionalization effect of the catalyst, the interaction between the catalyst and a substrate can be greatly improved, so a reaction can obtain higher catalytic activity and stereoselectivity.
