Bidirectional, Organocatalytic Synthesis of Lepidopteran Sex Pheromones
摘要:
Shuffling of two simple building blocks and a regioselective transfer hydrogenation allow for the rapid synthesis of a small collection of lepidopteran sex pheromones, e.g., 8E,10Z-tetradeca-8,10-dienal 5c, from the horse chestnut leafminer (Cameraria ohridella).

activity associated with a subfamily of the tetramic acid class of natural products. Despite the fact that members of this subfamily act as protein–protein interaction inhibitors that are of relevance to proteasome assembly, no synthetic work has been reported. This may be due to the fact that this subfamily contains an unnatural 4,4‐disubstitued glutamic acid, the synthesis of which provides a key challenge
