Stereoselective synthesis of 2H-chromans by reductive deoxygenation of differently substituted 2-sulfinylmethylchroman-2-ols

Hernandez-Torres, Gloria,Carreno, M. Carmen,Urbano, Antonio,Colobert, Francoise

experimental part, p. 3864 - 3877 (2011/09/30)

Good-to-excellent diastereoselectivies have been achieved in the synthesis of 2H-chromans by Et3SiH/TMSOTf reductive deoxygenation of differently substituted 2-sulfinylmethylchroman-2-ols and their methyl ketals. The influence of both electron-
