Nucleophilic Addition of Potassium O-Ethyl Dithiocarbonate to Baylis-Hillman Adducts Using 9-BBN as Catalyst
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...
