资源简介：
Asymmetric bromolactonizations of
alkynes are possible using a
desymmetrization approach. The commercially available catalyst (DHQD)2PHAL promotes these cyclizations in combination with cheap
NBS as a bromine source to give bromoenol lactones in high yield and
with high enantioselectivity. The bromoenol lactone products, containing
a tetrasubstituted alkene and a quaternary stereocenter, are valuable
building blocks for synthetic chemistry.
