A chemoselective route which provides direct access to bicyclic tetramates, making use of Dieckmann cyclisation of functionalised oxazolidines and imidazolidines derived from an aminomalonate, is reported; calculations suggest that the observed chemoselectivity is kinetically controlled and leads to the thermodynamically most stable product. Some compounds in the library showed modest antibacterial activity against Gram-positive bacteria, and this activity is maximal in a well-defined region of chemical space (554 < < 722 g mol; 5.78 < cLogP < 7.16; 788 < MSA < 972 Å; 10.3 < rel. PSA < 19.08).
报告了一种利用功能化恶唑烷和咪唑烷的 Dieckmann 环化反应，直接合成双环四甲酸盐的化学选择性方法，这些恶唑烷和咪唑烷是由氨基丙二酸衍生而来的；计算表明，观察到的化学选择性是动力学控制的，导致热力学最稳定的产物。库中的一些化合物对革兰氏阳性菌表现出适度的抗菌活性，这种活性在化学空间的一个明确区域内达到最大值（554 < < 722 g mol; 5.78 < cLogP < 7.16; 788 < MSA < 972 Å; 10.3 < rel. PSA < 19.08）。
