Title: Stereoselective titanium-mediated aldol reactions of a chiral isopropyl ketone. Author: Zambrana J, Romea P, Urpí F. Journal: Chem Commun (Camb); 2013 May 18; 49(40):4507-9. PubMed ID: 23576096. Abstract: A novel substrate-controlled aldol reaction of a chiral isopropyl ketone is reported. The outstanding regioselective enolization by TiCl4-i-Pr2NEt provides a chelated enolate that can participate in highly diastereoselective additions to a wide array of aldehydes favouring the corresponding 2,5-syn adducts.[Abstract] [Full Text] [Related] [New Search]
