Haessig, Robert,Siegel, Herbert,Seebach, Dieter
, p. 1990 - 1997 (2007/10/02)
The bromohydrins (C, 2, 5) from α-bromolithiocyclopropanes and aldehydes or ketones can be O-silylated quantitatively by chloro- or iodotrimethylsilane/hexamethyldisilazane/pyridine.Treatment of the product (3, 6) thus obtained with tert-butyllithium at -
