Hashimoto, Takuya,Maruoka, Keiji
, p. 10054 - 10055 (2007)
An axially chiral dicarboxylic acid has been prepared as a new class of chiral hydrogen-bonding catalysts and applied to the highly enantioselective Mannich reaction of arylaldehyde N-Boc imines and diazo compounds. Copyright
A New Asymmetric Synthesis of β-Aminophosphonic Acids
Mikolajczyk, Marian,Lyzwa, Piotr,Drabowicz, Jozef
, p. 357 - 358 (2007/10/03)
Addition of α-phosphonate carbanions to (S)-sulfinimines 2 gives N-sulfinyl-β-aminophosphonates 3 with a high diastereoselectivity (up to 10:1).The major diastereometer of 3 (R=Ph) was converted into (+)-(R)-β-amino-β-phenylethanephosphonic acid 5. - Keyw
