Highly diastereoselective addition of ketone enolates to N-sulfinyl imines: Asymmetric synthesis of syn- and anti-1,3-amino alcohol derivatives
Kennedy, Andrew,Nelson, Adam,Perry, Alexis
, p. 967 - 970 (2007/10/03)
Lithium enolates derived from ketones may be added to N-sulfinyl imines with high diastereoselectivity. Diastereoselective reduction gave either the syn- or anti-1,3-amino alcohol derivative.
