Chemical Properties

WHITE AMORPHOUS POWDER

Uses

Nα-Boc-L-asparagine is an N-Boc-protected form of L-Asparagine (A790005). L-Asparagine was first isolated by Robiquet and Vauquelin from asparagus juice (a high source of L-asparagine). L-Asparagine is often incorporated into proteins, and is a basis for some cancer therapies as certain cancerous cells require L-asparagine for growth.

Definition

ChEBI: The Nalpha-t-butoxycarbonyl derivative of L-asparagine

reaction suitability

reaction type: Boc solid-phase peptide synthesis

Synthesis

70-47-3

24424-99-5

7536-55-2

L-asparagine (15 g, 0.113 mol, 1.0 eq.) and sodium carbonate (12 g, 0.113 mol, 1.0 eq.) were dissolved in a solvent mixture of water (225 mL) and 1,4-dioxane (225 mL) at room temperature. To this solution was slowly added di-tert-butyl dicarbonate (30 g, 0.137 mol, 1.2 eq.) and the reaction mixture was stirred overnight at room temperature. Upon completion of the reaction, 1,4-dioxane was removed by distillation under reduced pressure. Subsequently, the pH of the solution was adjusted to 2 with 37% hydrochloric acid, at which point a white solid precipitated. The solid product was collected by filtration, washed with water and dried under appropriate conditions. Finally, 24 g of BOC-L-asparagine was obtained in 91% yield. The product characterization data were as follows: melting point 175°C-180°C (literature value 175°C); 1H NMR (DMSO-D6) δ 12.5 (1H, br); 7.31 (1H, br); 6.91 (1H, br); 6.87 (1H, d, J=8.4 Hz); 4.23 (1H, q, J=7.7 Hz); 2.56- 2.36 (2H, m); 1.38 (9H, s).
