AbstractThe addition of metalated alkynes to acylsilanes leads to the corresponding α‐propargylsilanol derivatives. On addition of ZnBr2, Zn‐promoted Brook rearrangements take place to produce the propargyl/allenylzinc bromides, which undergo cyclization to give functionalized carbocycles as single diastereoisomers.
