Relative Structure

Alotamide is a cyclic depsipetide isolated from a marine cyanobacterium and possesses a unique activation of calcium influx in murine cerebrocortical neurons (EC50 4.18 µM). Due to its limited source, the three stereocenters (C19, C28, and C30) in its polyketide fragment remain undetermined. In this study, the first asymmetric synthesis of its polyketide fragment was achieved. Four relative possible diastereomers were constructed with a boron-mediated enantioselective aldol reaction and Julia–Kocienski olefination as the key steps. Comparison of 13C NMR spectra revealed the relative structure of fragment C15–C32 of alotamide.

Steric Control

A synthesis of the optically inactive form of the natural sesquiterpene davanone (1)together with three stereoisomers has been carried out as in Scheme. Although not subject to steric control, the synthesis confirms the structure of davanone, and leads to the suggestion that the relative stereochemistry may be that shown in (16). The preparation and some reactions with carboxylic acids of 3-methylbut-2-enyllithium are described.
