Catalytic asymmetric prop-2-ynylation involving the use of the bifunctional synergetic reagent Et2BSPri

Article abstract of DOI:10.1039/a700540g

Efficient catalytic asymmetric prop-2-ynylation of achiral aldehydes with allenyltributylstannane promoted by a BINOL-Ti^IV complex (10 mol%) is achieved with high enantioselectivity by the use of Et₂BSPrⁱ.
