Abstract

The title compound, C(10)H(9)NO(3), is a chiral mol-ecule with one stereogenic carbon atom, but which crystallizes as a racemate in the centrosymmetric space group P2(1)/n. The central six-membered ring of the indolizine moiety adopts a definite envelope conformation, while the conformation of the oxopyrrolidine ring is close to that of a flat-envelope with a maximum deviation of 0.352 (1) Å for the flap atom.

摘要

标题化合物C(10)H(9)NO(3)是一种具有一个手性碳原子的手性分子，但它以消旋体形式结晶于中心对称空间群P2(1)/n中。中氮茚部分的中心六元环呈现出确定的信封式构象，而氧代吡咯烷环的构象接近扁平信封式，其翼片原子的最大偏差为0.352 (1) Å。
