The absolute configuration of the title compound, C(10)H(17)NO(3)·H(2)O, was assigned from the synthesis. In the mol-ecular structure, the central six-membered ring of the indolizine moiety adopts a chair conformation, with two atoms displaced by -0.578 (2) and 0.651 (1) Å from the plane of the other four atoms [maximum deviation 0.019 (2) Å] The conformation of the fused oxopyrrolidine ring is close to that of a flat envelope, with the flap atom displaced by 0.294 (1) Å from the plane through the remaining four atoms. In the crystal, one of the hy-droxy groups is hydrogen-bonded to two water mol-ecules, while the other hy-droxy group exhibits an inter-molecular hydrogen bond to the carbonyl O atom, resulting in a chain parallel to the b axis.
标题化合物C(10)H(17)NO(3)·H(2)O的绝对构型通过合成确定。在分子结构中，中氮茚部分的中心六元环呈椅式构象，有两个原子相对于其他四个原子所在平面的位移分别为-0.578(2) Å和0.651(1) Å[最大偏差0.019(2) Å]。稠合的氧代吡咯烷环的构象接近扁平信封式，瓣状原子相对于通过其余四个原子的平面的位移为0.294(1) Å。在晶体中，其中一个羟基与两个水分子形成氢键，而另一个羟基与羰基O原子形成分子间氢键，形成平行于b轴的链。
