Intramolecular radical hydrosilylations using allyloxy- and propargyloxycyclohexadienylsilanes comprising 5-endo-trig as well as 5-endo-dig processes are presented.
In search of open-chain 1,3-stereocontrol

Methylation of methyl 4-phenylpentanoate 25 gives the diastereoisomers methyl (2RS,4SR)-2-methyl-4-phenylpentanoate 26 and methyl (2RS,4RS)- 2-methyl-4-phenylpentanoate 27 in a ratio of 44:56. The aldehydes 3-dimethyl(phenyl)silylbutanal 28, 3-dimethyl(ph
The Regiochemistry and Stereochemistry of the Hydroboration of Allylsilanes
Fleming, Ian,Lawrence, Nicholas J.
, p. 3309 - 3326 (2007/10/02)
The hydroboration of a wide range of allylsilanes 3 and 5-21 is found to be generally regioselective for attachment of the boron to C-3 and hydrogen to C-2 of the allyl unit, and to be generally stereoselective in the sense 1, with attachment of the boron
STEREOCHEMISTRY IN THE HYDROBORATION OF ALLYLSILANES
Fleming, Ian,Lawrence, Nicholas, J.
, p. 2077 - 2080 (2007/10/02)
The hydroboration of allylsilanes is highly stereoselective in the sense (3 -> 4 and 6->7), especially with 9-BBN as the hydroborating reagent.The products can be converted stereospecifically into 1,3-diol derivatives (5 and 8).
REGIOCHEMISTRY IN THE HYDROBORATION OF ALLYLSILANES
Fleming, Ian,Lawrence, Nicholas, J.
, p. 2073 - 2076 (2007/10/02)
The hydroboration of most types of allylsilane is highly selective for the formation of the product having the silicon and boron in a 1,3 relationship when the hydroborating agent is 9-BBN.There is only a low degree of correlation between the difference in the chemical shifts of the trigonal carbon atoms on an alkene and the regioselectivity in hydroboration with either borane:THF or 9-BBN.
