Versuchsvorschrift

To a stirring solution of (R)-2-methylpropane-2-sulfinamide (326 mg, 2.69 mmol) and Intermediate 12A (600 mg, 2.82 mmol) in THF (2 mL) at rt was added tetraethoxytitanium (1.06 mL, 5.12 mmol). The reaction mixture was heated at 75° C. for 16 h. The reaction mixture was cooled and used directly in the next step. LCMS=2.12 min [M+1]=318.0 (Method B).
