Netz, Astrid published the artcileFacial diastereoselectivity in cationic propargylations with planar-chiral areneCr(CO)3-substituted propargyl cations, Application In Synthesis of 924-99-2, the publication is European Journal of Organic Chemistry (2005), 1823-1833, database is CAplus.
The planar-chiral (o-methoxyphenyl)chromium tricarbonyl-substituted propargyl cation reacts with silyl enol ether derivatives with poor and with enamines with good facial diastereoselectivity to give rise to the (arene)carbonylchromium-substituted propargylated cyclohexan-2-ones, and carboxylic acid, γ-lactone, cyclopentan-2-one, and esters. Structural correlations were unambiguously deduced from x-ray structure. The origin of facial diastereoselectivity with this class of organometallic electrophiles lies in steric and stereoelectronic biases rather than in purely electronic nucleophilicity.
