Electric Literature of 115652-52-3, In the chemical reaction process,reaction time,type of solvent,can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product.An updated downstream synthesis route of 115652-52-3 as follows.
Example 1Synthesis of: (/?)-3-((/?)-2-amino-3-(l-(hvdroxymethyl)cvclopropylamino)-3-oxopropylthio) propane- 1,2-diyl didodecanoateStep 1: (R)-3-((R)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-(l-(hydroxymethyl)cyclo- propylamino)-3-oxopropylthio)propane-l,2-diyl didodecanoate[000398] To a solution of (5«,9«)-9-(dodecanoyloxy)-l-(9H-fluoren-9-yl)-3,12-dioxo-2,l l- dioxa-7-thia-4-azatricosane-5-carboxylic acid (6, 1 eq) and HBTU (1.2 eq) in DCM (0.06 M) was added DIEA (3.5 eq), followed by (1-aminocyclopropyl) methanol hydrochloride (1.2 eq). The reaction was stirred at room temperature for 2 hours. The crude mixture was purified by flash chromatography on a COMBIFLASH system (ISCO) using 30-50% EtO Ac/Hex to give (R)-3- ((R)-2-(((9H-fluoren-9-yl)methoxy)carbonylamino)-3-(l-(hydroxymethyl)cyclopropylamino)-3- oxopropylthio)propane- 1 ,2-diyl didodecanoate.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,115652-52-3, its application will become more common.
