Abstract: The present application relates to a new method for synthesizing isophosphoramide nitrogen mustard (X-IPM) that is suitable for industrialized production, involves fewer types of solvents, and leads to stable products with high yield. This method is charazterized mainly by the batchwise addition of M (e.g., M is R3N with R being ethyl; i.e., M is triethylamine) and the specific post-reaction treatment, which make it possible for the reaction to fully proceed, lead to products with less impurities, high yield and relatively stable properties, and can lead to stable crystallized substances with specific crystal structures. The present application also relates to stable crystal forms of the isophosphoramide nitrogen mustard (X-IPM) prepared by the aforementioned method, and use of the same as reactants for the synthesis of aziridine structure-containing compounds.

Abstract: The invention provides a method for constructing a target prediction model in a multicenter small sample scenario and a prediction method. In combination with the idea of transfer learning, a training set of a new node is predicted by directly using knowledge of a trained node, and a prediction error sample is used to reflect a difference between the new node and the trained node. The difference is used as supplementary knowledge. Model knowledge of the new node is quickly acquired, to avoid training of a new node from scratch each time. Finally, parallel integration of incremental subclassifiers is implemented by using a ridge regression method, so that the deployment time and costs are greatly reduced. The generalization of models is ensured through sharing of historical knowledge and a knowledge discarding mechanism, good classification effect can also be achieved for a node with a small sample size.
