The first total synthesis of RQN-18690A (18-deoxyherboxidiene) and the determination of its absolute stereochemical configuration are described. The synthesis features an organocatalytic aldol reaction for the first step, 1,4- and 1,2- dual reductions of α,β-unsaturated δ-lactone followed by a domino reaction in a one-pot operation, and diastereoselective epoxidation with kinetic resolution.
描述了RQN-18690A(18-脱氧herboxidiene)的第一个全合成及其绝对立体化学构型的确定。该合成的第一步是有机催化的羟醛反应,α,β-不饱和δ-内酯的1,4-和1,2-双重还原,然后在一个反应釜中进行多米诺反应以及具有动力学拆分能力的非对映选择性环氧化。
