실험 절차

To a stirred solution of methyl 3-thiomorpholinecarboxylate 1,1-dioxide (D16; 1.08 g, 5.6 mmol) in 14 ml of anhydrous 1,2-dichloroethane was added N-boc-2-aminoacetaldehyde (1.1 g, 6.7 mmol) and acetic acid (0.316 ml, 5.6 mmol). After 30 min. sodium triacetoxyborohydride (1.78 g, 8.4 mmol) was added and the solution stirred at room temperature. Additional aliquots of N-boc-2-aminoacetaldehyde and sodium triacetoxyborohydride (1.0 g, 4.7 mmol) were added and the reaction continued overnight.
