(14) The crude 1H-NMR spectra show remaining alkyne
substrate after finished reaction. The alkynes used for
this methodology are inexpensive and therefore
reisolation was considered irrelevant. Nevertheless,
trying to reisolate the alkyne after the coupling of 1-
octyne with p-methylbenzoic acid resulted in 0.7 eq. of
the alkyne being reisolated.

(16) Ligands in Table 1 are a selection of the ligands screened
and/or synthesized. Most standard classes of chiral
ligands
commercially
available
were
screened
unsuccessfully, with good results exclusively for ligands
with a C4 backbone.

(19) Unfortunately, a reaction with 5-hydroxy-1-pentyne as
the alkyne substrate resulted in the desired product with
less than 40% conversion (97 :3 B:M ratio). A protection
of the alcohol seems to be important in this chemistry in
order to achieve higher conversions.
(20) Additionally, 3-phenyl-1-propyne was tested in the
reaction, giving the desired allylic ester only in very low
conversion (<10%) and with no enantiomeric excess. As a
side reaction homocoupling of the alkyne was observed.

(29) The kind of flask used is important for a successful
reaction. It appears that the reaction is very sensitive to
air and therefore the tighter seal utilizing a teflon screw
cap is essential. A picture of the kind of flasks used for
this coupling can be found in the supporting
information.
