  Synthesis of poison-frog alkaloids 233A, 235U, and 251AA and their inhibitory effects on neuronal nicotinic acetylcholine receptors

  摘要：

  We previously reported that the synthetic quinolizidine 1-epi-2071 is a relatively selective blocker of 0 nicotinic acetylcholine receptors. We now synthesized the analogous poison frog alkaloids 233A, 235U, and 251AA, and investigated the biological activities at two major types of neuronal nicotinic receptors. Electrophysiological study showed that the alkaloid 233A blocked alpha 7 and alpha 4 beta 2 currents with similar potencies. Alkaloids 235U and 251AA also showed similar potencies for blockade of a7 and alpha 4 beta 2 currents. Thus, based on these studies, it would appear that C4 substituents greater in length than the allyl of 1-epi-2071 reduce alpha 7-potency without affecting alpha 4 beta 2-potency.

  Amidopalladation of Alkoxyallenes Applied in the Synthesis of an Enantiopure 1-Ethylquinolizidine Frog Alkaloid

  摘要：

  A palladium-catalyzed amidation of alkoxyallenes has been developed for the construction of linear allylic N,O-acetals under basic conditions involving (cyclic) amides, sulfonamides, carbamates, and amidophosphates. Application of the methodology provided access to the enantiopure 1-ethylquinolizidine structural motif, which is a key synthon in the synthesis of the naturally occurring poisonous frog quinolizidine 233A and derivatives such as the 1-epi-isomer of quinolizidine 207I.
