Application of amide-stabilized sulfur ylide reactivity to the stereodivergent synthesis of (R,S)- and (S,R)-reboxetine
摘要:
A simple access to (RS)- and (S,R)-reboxetine from a single chiral sulfonium salt 4 is reported. This approach, based on a stabilized sulfur ylide-mediated epoxidation, followed by a regioselective opening reaction, enables the preparation of these two potentially biologically active compounds in 35.6% and 13.7% overall yield.
