WebAug 6, 2024 · The total synthesis of cytotoxic meroditerpenoid naphthoquinone derivative chabrolonaphthoquinone B (1) in an enantiospecific manner is divulged using a chiral pool approach. The key step of our synthetic route is a modified Julia olefination between a sulfone-bearing aliphatic fragment and a … WebMar 12, 2004 · The chiral pool approach to synthesis of optically active targets can be extremely attractive if nature happens to provide an abundant supply of a starting material appropriate for the synthetic target. Accordingly, considerable effort and creativity has been directed toward using inexpensive chiral pool elements in target-oriented synthesis ...

The broad applicability of this approach is demonstrated with the short (eight-step) synthesis of four natural products and three analogues. These syntheses are the first of any members of the acyclic polyhalogenated Plocamium tso-c112

The chiral-pool approach starts with malic acid and employs only highly reliable reactions such as Wittig reactions, protecting group conversions, and reductions. Depending on the configuration of malic acid being used as starting material both enantiomers can … WebChiral auxiliaries are enantiomerically pure compounds derived mostly from inexpensive chiral natural sources (i.e. chiral pool, see Section 2.13.1).The use of a chiral auxiliary in asymmetric synthesis is referred to as second-generation (2G) asymmetric synthesis.
