Synthesis of a N-Boc-protected piperidin-2-yl phosphine oxide starting from piperidine in three steps, followed by olefination using a variety of α,β-unsaturated aldehydes resulted in tert-butyl 2-(2′- alkenylidene)piperidine-1-carboxylates in high yields
Total syntheses of (±)-cryptopleurine, (±)-antofine and (±)- deoxypergularinine
Lebrun, Stephane,Couture, Axel,Deniau, Eric,Grandclaudon, Pierre
, p. 2659 - 2670 (2007/10/03)
The alkaloids (±)-cryptopleurine 1, (±)-antofine 2, and (±)- deoxypergularinine 3 were synthesized by Pictet-Spengler cyclization of the 2-arylmethylpiperidine and -pyrrolidines 4, 5 and 6 obtained by sequential N- deprotection-reduction of the parent ene
