Abstract
Catalytic enantioselective hydrogen autotransfer reactions for the direct conversion of lower alcohols to higher alcohols are catalogued and their application to the total synthesis of polyketide natural products is described. These methods exploit a redox process in which alcohol oxidation is balanced by reductive generation of organometallic nucleophiles from unsaturated hydrocarbon pronucleophiles. Unlike classical carbonyl additions, premetalated reagents, chiral auxiliaries and discrete alcohol-to-aldehyde redox reactions are not required. Additionally, chemoselective dehydrogenation of primary alcohols in the presence of secondary alcohols enables C-C coupling in the absence of protecting groups.

Abstract
Amphidinolides C, F, and U, including C2-C4 analogs, are highly cytotoxic marine macrolides, mainly isolated from dinoflagellates of the genus Amphidinium. All these polyketides share a 75 % or more similar structure, highlighted by a macrolactone ring, at least one trans-2,5-substituted-THF motif and a characteristic polyenic side chain. From their isolation and absolute configurational assignment, the total synthesis of these marine macrolides represented an intense challenge to the organic synthesis community over the last 15 years, with around 14 research groups engaged in this inspiring task. In the first part of this review, we present the different approaches to the isolation and characterization of these natural products, including the most recent analogs, which may cast doubt on the biogenetic origin of these compounds. The various synthetic approaches to the total synthesis of C, F, and U amphidinolides are presented in a second part, focusing on key reactions and/or innovative strategies. The review concludes in a third section summarizing the successful approaches leading to the total synthesis of one of the members of this amphidinolide subfamily.

Abstract
Exploration of an ambitious new strategy for the total synthesis of the cytotoxic marine natural product amphidinolide F is described, which features fabrication of the core structure from four readily accessible fragments and macrocycle construction through C9-C10 bond formation by intramolecular Stille coupling between an alkenyl iodide and alkenyl stannane. Efficient stereoselective synthesis of each of the four building-blocks and subsequent coupling of them to produce the requisite cyclization precursor has been accomplished, but suitable conditions for high-yielding palladium-mediated closure of the macrocycle to produce the fully protected amphidinolide F ring system have yet to be identified.

Abstract
![]()
The complete carbon
framework of the macrocyclic marine natural
product amphidinolide F has been prepared by a convergent synthetic
route in which three fragments of similar size and complexity have
been coupled. Key features of the syntheses of the fragments include
the stereoselective construction of the tetrahydrofuran in the C1–C9
fragment by oxonium ylide (free or metal-bound) formation and rearrangement
triggered by the direct generation of a rhodium carbenoid from 1-sulfonyl-1,2,3-triazole,
the highly diastereoselective aldol reaction between a boron enolate
and an aldehyde with 1,4-control to prepare the C10–C17 fragment,
and the formation of the tetrahydrofuran in the C18–C29 fragment
by intramolecular nucleophilic ring opening of an epoxide with a hydroxyl
group under acidic conditions.

Abstract
Amphidinolides F, C, C2, and C3 are marine natural products isolated from dinoflagellates Amphidinium species. They share the same macrolactone core, with the difference between them residing at the side chain level. A predominant feature of these amphidinolides is the presence of two trans-THF rings inside the macrolactone core, which is thought to be built by C-glycosylation with titanium enolate of N-acetyl oxazolinethiones. Thus, the original strategy for their total synthesis was based on the assembly of three main fragments corresponding to C1-C9, C10-C19, and C20-C29 or C20-C34 disconnections. Whereas synthesis of all fragments was successful, the C-glycosylation reaction between C19 and C20 turned out to be an issue. Therefore, a second route was designed. The new disconnection between C17 and C18 was based on a sulfone addition and a desulfonylation sequence. Our convergent strategy allowed the total synthesis of amphidinolide F and enabled a new unifying route toward the synthesis of amphidinolides C, C2, and C3 using a late-stage divergent approach. Although there were unsatisfying yields at some critical steps, our work culminated into the first total synthesis of amphidinolide C2.
