Paragraph 0065-0069, (2020/11/05)
The invention discloses a synthetic method of 3-hydroxyazetidine hydrochloride, and belongs to the field of pharmacy. The synthetic method of the 3-hydroxyazetidine hydrochloride comprises the following steps: introducing hydrogen chloride gas into a solution formed by N-(triphenylmethyl)-3-hydroxyazetidine and a first organic solvent to carry out a reaction of removing triphenylchloromethane, andcarrying out solid-liquid separation to obtain the 3-hydroxyazetidine hydrochloride. The period for preparing the 3-hydroxyazetidine hydrochloride by utilizing the synthesis method is short, the safety is good, the use of toxic or expensive reagents is avoided, the reaction yield is high, the 3-hydroxyazetidine hydrochloride with high quality purity can be obtained, the operation is simple and convenient, and the method is suitable for large-scale industrial production.

Polylactide (PLA) is a fully biodegradable and recyclable plastic, produced from a bio-derived monomer: it is a circular economy plastic. Its properties depend upon its stereochemistry and isotactic PLA shows superior thermal-mechanical performances. Here, a new means to control tacticity by exploiting rotaxane conformational dynamism is described. Dynamic achiral [2]rotaxanes can show high isoselectivity (Pi=0.8, 298 K) without requiring any chiral additives and enchain by a chain end control mechanism. The organocatalytic dynamic stereoselectivity is likely applicable to other small-molecule and polymerization catalyses.
