HERNANDEZ-IBINARRIAGA, Ilsa  y  MIRANDA, Luis D.. Nucleophilic Addition of Potassium O-Ethyl Dithiocarbonate to Baylis-Hillman Adducts Using 9-BBN as Catalyst. J. Mex. Chem. Soc [online]. 2009, vol.53, n.2, pp. 55-58. ISSN 1870-249X.

An efficient diastereoselective Michael addition of the commercial potassium O-ethyl dithiocarbonate to Baylis-Hillman adducts in the presence of 9-BBN (9-borabicyclo[3.3.1]nonane) as a Lewis acid is reported. 9-BBN both protected the hydroxyl group and activated the carbonyl of the Michael acceptor.

Palabras llave : Xanthates; Baylis-Hillman adducts; 9-BBN as a Lewis acid.
