Ginchona alkaloid derivatives with natural configuration at C-3 have been constructed by Grignard reaction of protected rubanone 1-TBDS. The organomagnesium regent attacks preferentially from the sterically more hindered endo face. Even L-Selectride(R) reacts endo-selectively (9 : 1). (C) 1997 Elsevier Science Ltd.
