Efficient syntheses of quinolizidine-type poison-frog alkaloids via Michael-type conjugate addition. (1st April 2018) - Zhou, De-Jun
Efficient and flexible syntheses of 1, 4-disubstituted quinolizidine-type poison-frog alkaloids using the highly stereoselective Michael-type conjugate addition reaction as the key step are described. The 1, 4-disubstituted quinolizidine poison-frog alkaloids 233A, 235U and 251AA are reported.
