trans-4-tert-Butyldimethylsiloxy-L-proline displays a greater catalytic activity than the parent proline without compromising the enantioselectivity, which widens the substrate scope in the α-aminoxylation of carbonyl compounds, as well as O-nitroso-aldol/Michael, and Mannich reactions.
反式-4-叔丁基二甲基甲硅烷氧基L-脯氨酸显示出比母体脯氨酸更大的催化活性,而不损害对映选择性,这扩大了羰基化合物以及O-亚硝基-醛醇/ Michael的α-氨基羟化反应中的底物范围,和曼尼希反应。
