The diastereo- and/or enantioselection are described in the title rearrangement of the chiral 2-(2-alkenyloxy)methyl 2-oxazolines which eventually provides optically active α-hydroxy, γ,δ- unsaturated esters and (+)-verrucarinolactone.
Synthesis and characterization of 2-[di(cyclopentadienyl)zircona]-1-oxacyclopentanes. X-Ray crystal structure of [(η-C<sub>5</sub>H<sub>5</sub>)<sub>2</sub>ZrOCH<sub>2</sub>CH<sub>2</sub>CHMe]<sub>2</sub>
2-[Di(cyclopentadienyl)zircona]-1oxacyclopentanes have been synthesized, isolated, and characterized by spectroscopin and X-ray analyses which show that they are dimeric with five co-ordinated bent metallocene structures; the mechanisms of their thermal decomposition have also been studied.
2-[Di(cyclopentadienyl)zircona]-1oxacyclopentanes 已被合成、分离,并通过光谱分析和 X 射线分析进行了表征,结果表明它们是具有五个配位弯曲茂金属结构的二聚体;同时还研究了它们的热分解机理。
