| titleOfInvention | A kind of L-grass ammonium phosphine-N-carboxylic acid anhydrides and preparation and application |
| abstract | The invention discloses a kind of L-grass ammonium phosphine-N-carboxylic acid anhydrides and preparation and application, described method taking have a liking for nicotine arthrobacterium WYG001 through fermented and cultured obtain wet thallus or the dry mycelium of wet thallus after freeze drying as enzyme source, taking DL-grass ammonium phosphine-N-carboxylic acid anhydrides as substrate, with pH7.0, the phosphate buffer of 0.1mol/L is reaction medium, at 20～50 DEG C, under 200rpm condition, react, after reacting completely, by reactant liquor separation and purification, obtain L-grass ammonium phosphine-N-carboxylic acid anhydrides, make L-grass ammonium phosphine through hydrolysis decarboxylic reaction again, the regioselectivity of thalline provided by the invention is strong, reaction conversion ratio is high, downstream separation is simple, energy consumption is low, environmental pollution is little, be applicable to suitability for industrialized production, L-grass ammonium phosphine-N-carboxylic acid anhydrides just can obtain optically pure L-grass ammonium phosphine through simple heating hydrolysis decarboxylation. |
