ales generated from the corresponding propargylic acetals rearrange in the presence of boron trichloride thus opening an efficient and convenient route to a variety of homopropargylic alcohols free of the corresponding allenic isomers. Unexpectedly, the parent derivative leads exclusively to the allenic alcohol.
在三氯化硼的存在下,由相应的炔丙基缩醛产生的硫代烷基炔有机硼酸盐可以重排,从而为各种不含相应的烯丙基异构体的高炔丙基醇打开了一条有效而便捷的途径。出乎意料的是,母体衍生物仅导致烯丙醇。
