Abstract
Reaction of functionalized alkyl 2-alkynoates (e.g., 13–19) with lithium (trimethylstannyl)(cyano)cuprate (3) under two sets of carefully defined experimental conditions provides, efficiently and stereoselectively, either alkyl (Z)- or (E)-3-trimethylstannyl-2-alkenoates (e.g., 23, 26–31 and 24, 32–37, respectively).Keywords
