Table 3. Substrate scope of the (Z/E)-isomera,b,c,d,e.
|
Reaction conditions same as in Table 2.
Isolated yields of the major product anti-2.
Diastereoselectivity was observed to be >20 : 1 for the major isomer, which was confirmed by 1H NMR analysis.
Unable to find the ratio of major and minor products in the crude 1H NMR analysis.
Enantioselectivity of the major isomer. SM = starting material.
