title: Synthesis of poison-frog alkaloids 237D, 207A, and two congeners of 235B' for evaluation to inhibitory effect of nicotinic acetylcholine receptors.
abstract: Enantioselective synthesis of the poison-frog alkaloids 237D, 207A, and two congeners of 235B' has been achieved. The absolute stereochemistry of 237D was determined to be 5S, 8S, 9R by the present synthesis.
