cyclization reaction is a straightforward route to the synthesis of 3-substituted prolines. Herein we report the application of this reaction to the syntheses of proline chimeras of lysine, glutamic acid, glutamine, arginine, and serine. All these compounds were obtained in enantiomerically pure form and suitably protected for peptide synthesis.
氨基-锌-烯-烯酸酯环化反应是3-取代脯氨酸合成的直接途径。本文中我们报道了该反应在赖氨酸,谷氨酸,谷氨酰胺,精氨酸和丝氨酸脯氨酸嵌合体的合成中的应用。所有这些化合物均以对映体纯形式获得,并适当保护用于肽合成。
