Adding a certain compound to certain chemical reactions, such as: 59101-28-9, 16-Bromohexadecan-1-ol, 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, HPLC of Formula: C16H33BrO, blongs to alcohols-buliding-blocks compound. HPLC of Formula: C16H33BrO
11.1 Diethyl 2-[(tert-butoxycarbonyl)amino] -2-(1 6-hydroxyhexadecyl)malonate10461] Diethyl 2-(tert-butoxycarbonyl)amidomalonate 2 (1.18 g, 3.80 mmol, purity: 89% (GC), 1.1 eq.) obtained as in example 1.2, bromide 15 (1.11 g, 3.40 mmol) obtained as in example 4.2 and caesium carbonate (2.35 g, 7.20 mmol, 2.1 eq.) were suspended in acetonitrile (20 mE) and heated to reflux for 6 h. After cooling to tt. the mixture was adsorbed on silica gel (3 g) and the product was purified by column chromatography (21 x3 cm, cyclohexane/ethyl acetate, 4:1 – 100% ethyl acetate) and isolated as white solid.
