Syntheses and Synthetic Applications of Stannylated Allylic Alcohols
摘要:
Allenyl carbinols undergo regioselective hydrostannation in the presence of MoBl(3), a catalyst originally developed for the hydrostannation of alkynes, giving rise to allyl stannanes, These allyl stannanes can easily be converted into useful synthetic building blocks such as allyl iodides or vinyl epoxides.

Allenylcarbinols undergo regioselective hydrostannation in the presence of MoBl3, a catalyst which was developed for the hydrostannation of propargyl alcohols and derivatives; allylstannanes are formed preferentially, which can easily be converted into allyl iodides.

was formed between the center carbon atom of the allene moiety and the hydroxyl oxygen, which was established by the X-ray single crystal diffraction study of gamma-lactone 3p. The highly opticallyactive 3-chloromethyl-2(5H)-furanones could be easily prepared from the readily available opticallyactive 2,3-allenols. A mechanism for this reaction was proposed.
