Adding a certain compound to certain chemical reactions, such as: 4461-39-6, N-(2-Hydroxyethyl)-1,3-propanediamine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 4461-39-6, blongs to alcohols-buliding-blocks compound. Recommanded Product: 4461-39-6
General procedure: A suspension oftert-butyl 4-((1R,3aS,5aR,5bR,7aR,11aS,11bR,13aR,13bR)-3a-formyl-5a,5b,8,8,11a-pentamethyl-1-(prop-1-en-2-yl)-2,3,3a,4,5,5a,5b,6,7,7a,8,11,11a,11b,12,13,13a,13b-octadecahydro-1H-cyclopenta[a]chrysen-9-yl)benzoate5(1 eq.), the corresponding amine (2 eq.) and acetic acid (2 – 5 eq.) in DCE (2 ml) was stirred at RT for 30 min.To this suspension was added sodium triacetoxyborohydride (5 eq.).The resulted mixture was stirred at RT for 18 – 72 hrs.The reaction mixture was diluted with 5 ml of saturated sodium carbonate and extracted with DCM (3 x 10 ml).The combined organic layers were dried over sodium sulfate, filtered and concentratedinvacuo.The crude product was purified by Biotage flash chromatography or was used directly in the next step without further purification.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,4461-39-6, N-(2-Hydroxyethyl)-1,3-propanediamine, and friends who are interested can also refer to it.
