nols allows the stereoselective formation of 2H-chromans with up to 95:5 diastereoisomeric ratio. This new methodology was appliedin a short and convergent enantioselective synthesis ofthe (S,R,R,R)-enantiomer of the antihypertensive drugNebivolol.(© Wiley-VCH Verlag GmbH & Co.

2-(p-tolylsulfinyl)methyl-2-chromanol 的同手性亚砜定向还原脱氧允许立体选择性形成 2H-色满,非对映异构体比例高达 95:5。这种新方法被应用于抗高血压药物奈必洛尔的 (S,R,R,R)-对映异构体的短而收敛的对映选择性合成。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
