chiral derivatizing agents, 3-arylcarbonyl-2,2-dimethyl-oxazolidine-4-carboxylic acids (N-arylcarbonylpseudoprolines), were prepared through a simple, short-step synthesis. The absolute configuration of secondary alcohols can be assigned on the basis of the NMR spectroscopic chemical shift difference between diastereomeric pseudoproline esters. Preparation of more efficient agents was achieved simply
新的手性衍生剂 3-芳基羰基-2,2-二甲基-恶唑烷-4-羧酸(N-芳基羰基假脯氨酸)是通过简单、短步合成制备的。仲醇的绝对构型可以根据非对映体假脯氨酸酯之间的 NMR 光谱化学位移差异来确定。简单地通过使用具有更强各向异性作用的芳族基团来制备更有效的药剂。
