  • Chiral Frustrated Lewis Pairs Catalyzed Highly Enantioselective Hydrosilylations of Ketones
    作者:Xiaoqin Liu、Qiaotian Wang、Caifang Han、Xiangqing Feng、Haifeng Du
    DOI:10.1002/cjoc.201900121
    日期:2019.7
    A highly enantioselective Piers‐type hydrosilylation of simple ketones was successfully realized using a chiral frustrated Lewis pair of tri‐tert‐butylphosphine and chiral diene‐derived borane as catalyst. A wide range of optically active secondary alcohols were furnished in 80%—99% yields with 81%—97% ee's under mild reaction conditions.

  • Rh Soaked in Polyionic Gel:  An Effective Catalyst for Dehydrogenative Silylation of Ketones
    作者:Carine Thiot、Alain Wagner、Charles Mioskowski
    DOI:10.1021/ol0623670
    日期:2006.12.1
    A polyionic gel- soaked Rh catalyst allows the formation of synthetically useful diphenylsilyl ( DPS) enols under mild conditions. The reaction proceeds through dehydrogenative silylation of ketones, affording the kinetic silyl enol ether in good to excellent yields. The in situ formed DPS enols were directly involved, without purification, in one- pot aldol and Mannich condensations.
  • Catalytic Enantioselective Hydrosilylation of Ketones with Rhodium-Phosphite Complexes Containing a TADDOLate and a Dihydrooxazole Unit
    作者:Dieter K. Heldmann、Dieter Seebach
    DOI:10.1002/(sici)1522-2675(19990707)82:7<1096::aid-hlca1096>3.0.co;2-i
    日期:1999.7.7
    New types of chiral phosphorus/nitrogen ligands, capable of forming six-membered-ring metal chelates have been prepared from alpha,alpha,alpha',alpha'-tetraaryl-1,2-dioxolane-4,5-dimethanols (TADDOLs), PCl3, and dihydrooxazole alcohols (from amino acids) (7 in Scheme 1). The X-ray crystal structure of a Rh complex of one of these ligands, 8b, has been determined (Scheme 2 and Fig.). Enantioselective hydrosilylations of dialkyl and aryl alkyl ketones with Ph2SiH2/0.01 equiv. Rh-1.7 have been studied and found to provide secondary alcohols in enantiomer ratios of up to 97: 3 (Scheme 3 and Table). The ligand prepared from (R,R)-TADDOL and the (R)-valine-derived (R)-alpha,alpha-dimethyl-4-isopropyl-4,5-dihydro gives better results than the (R,R,S)-isomer (7d vs. 7c in Scheme 3), and an i-Pr group on the 4,5-dihydrooxazole ring gives rise to a slightly better selectivity than a Ph group. With the (R,R,R)-ligands the hydrogen transfer occurs from the Re face of the oxo groups (Sclleme 4).
