Paragraph 0223-0225, (2021/07/01)
The invention provides a method for preparing a long aliphatic chain diacid derivative. The method comprises the following steps of: (1) carrying out a cyclization reaction on long aliphatic chain diacid, the long aliphatic chain diacid having a structure as shown in a formula (A); (2) reacting the long aliphatic chain diacid cyclization product with benzyl alcohol to obtain long aliphatic chain diacid monobenzyl ester; (3) carrying out an esterification reaction on the long aliphatic chain diacid monobenzyl ester and N-hydroxysuccinimide so as to obtain long aliphatic chain diacid succinimide benzyl ester; (4) carrying out a nucleophilic addition amidation reaction on the long aliphatic chain diacid succinimide benzyl ester and a compound as shown in a formula (B) to obtain a compound as shown in a formula (C); (5) carrying out an esterification reaction on the compound as shown in the formula (C) and N-hydroxysuccinimide again so as to obtain a compound as shown in a formula (D); and (6) carrying out a debenzylation reaction on the compound shown in the formula (D) so as to obtain a compound shown in a formula (E).

, (2020/07/15)
The invention relates to the field of chemical organic synthesis, in particular to a preparation method of a long-chain diacid mono-benzyl ester compound. The preparation method comprises the following steps: taking long-chain dicarboxylic acid as an initial raw material, firstly preparing a dibenzyl ester compound, and then carrying out lithium hydroxide mono-hydrolysis to obtain the long-chain diacid mono-benzyl ester compound. The provided preparation method overcomes the defects of long steps, complex method, poor selectivity and low yield of a traditional process. Besides, the prepared long-chain diacid mono-benzyl ester compound is used as an important synthesis intermediate, has an active reaction group and can be used for preparing a series of long-chain compounds.

The tris(macrocycle)s that function in bilayer membranes as ion channels have recently shown versatile new applications such as antibiotic synergists and as agents for direct injection chemotherapy. This report records the development of new and versatile approaches to these molecules that produce significantly better overall yields for a group of previously reported hydraphiles having spacer chains ranging from octylene to hexadecylene.
