Supplemental Product Information:
Previously this product had been labeled as a hydrate form both in product name and molecular formula. The hydrate form had no exclusive CAS RN and used to share the same CAS RN as the anhydrous form.
To avoid any misleading information and since moisture in product is considered as an impurity, we have decided to remove the term 'Hydrate' from product name and 'xH2O' from the molecular formula for such products.
Please use it at ease since there is no difference in product quality, even if you see the previous indications on a part of label.

Application
Enantioselective Mannich Reaction of Malonates with N-tert-Butoxycarbonyl Imines
Typical Procedure:
A well-dried glass tube is charged with Yb(OTf)3 (30 mg, 0.048 mmol) and the ligand (44 mg, 0.096 mmol) under argon atmosphere. After dichloromethane (1.0 mL) is added to the mixture, it is stirred vigorously at room temperature for 1 h until the reaction become homogeneous. The imine (1 mmol) and dibenzylmalonate (neat, 0.312 g, 1.1 mmol) dissolved in dichloromethane are added to the solution of the complex under an argon atmosphere. After that methanol (1 mmol) is injected in one portion to the reaction mixture. After 12 h, the reaction mixture is purified by flash chromatography through a short column of silica gel using an eluting mixture of hexane / ethyl acetate solvent to obtain the corresponding products.
