Indium-mediated propargylation of aldehydes: Regioselectivity and enantioselectivity studies
Loh, Teck-Peng,Lin, Man-Jing,Tan, Kee-Leng
, p. 507 - 509 (2003)
An enantioselective propargylation reaction of aldehydes with enantioselectivity up to 85% has been achieved in organic solvents by using stoichiometric amounts of (-)-cinchonidine as the chiral source.
Silicon as a directing group in the phosphine-catalyzed [2 + 3]-cycloaddition of aryl allenones with electron-deficient olefins
Sampath, Magesh,Loh, Teck-Peng
supporting information; experimental part, p. 1568 - 1570 (2009/09/06)
This Communication describes a highly efficient phosphine-catalyzed [2 + 3]-cycloaddition reaction using α-trimethylsilyl-substituted aryl allenones and electron deficient olefins; both good yields and good asymmetric induction were obtained.
Regioselective addition reactions of propargyl bromides to carbonyl compounds with gallium catalyzed by indium
Lee, Phil Ho,Kim, Hyun,Lee, Kooyeon
, p. 1219 - 1222 (2007/10/03)
Reactions of organogallium reagents generated from propargyl bromides having substituents at the γ-position and gallium in the presence of 5 mol % of indium with aldehydes and ketones selectively produced homoallenyl alcohols in good to excellent yields.
