Diastereoselectivity in the Formation of Quaternary Centers with Aryllead(IV) Tricarboxylates
摘要:
[GRAPHICS]The formation of quaternary centers utilizing the reaction of aryllead(IV) tricarboxylates with beta-ketoesters has been investigated, A series of substituted methyl 2-oxo-1-cyclohexanecarboxylates served as substrates for the evaluation of diastereoselectivity in the sp(2)-sp(3) bond forming reaction with p-methoxyphenyllead tricarboxylates. Selectivities ranged from poor to excellent depending on the substituent. A comparison to iodonium salts is discussed.
