PROCEDURE

实验过程

A -5° C. solution of L-isoleucine, N-[1-(carboxymethyl)-L-prolyl] benzylamide (254 mg, 0.67 mmol, 1.0 eq), N-methylmorpholine (96 uL, 0.88 mmol, 1.30 eq) in acetonitrile (7 mL) was treated with isobutyl chloroformate (96 uL, 0.74 mmol, 1.1 eq) followed by 1,4-dioxa-8-aza-spiro[4.5] decane (0.193 g, 1.35 mmol, 2.0 eq). Purification by flash chromatography provided 280 mg (83%) of L-isoleucine, N-[1-(2-(1,4-dioxa-8-aza-spiro[4.5]dec-8-yl)-2-oxoethyl)-L-Prolyl] benzylamide as a colorless oil
