Highly chemoselective formation of aldehyde enamines under very mild reaction conditions
Abstract: Although ketone enamines are widely used in organic synthesis, aldehyde enamines are rarely employed due to the limitations of their preparation using known methods (need for acid or base, excess of amine, and/or ...
Short approach toward the nonracemic A,B,E tricyclic core of calyciphylline B-type alkaloids
Abstract: A suitably functionalized tricyclic adduct containing the common A,B,E rings found in calyciphylline B-type alkaloids was obtained in nine linear steps. The key transformation features an efficient one-pot sequence ...
