inherent double controlled strategy of sterically hindered propargyl alcohols without the installing of external directing groups. Its synthetic robustness and practicality have been illustrated by the concise synthesis of bervastatin, a hypolipidemic drug, and late‐stage modification of complex alkynes with precise regioselectivity.
The design of a spiro-pyrrolidine organocatalyst and its application to catalytic asymmetric Michael addition for the construction of all-carbon quaternary centers
A novel chiral spiro-pyrrolidine silyether organocatalyst has been designed. Its catalyticasymmetric effect is demonstrated by the Michaeladdition reaction, which affords the desired products with an all-carbon quaternarycenter...
