Abstract
Marine polycyclic ether natural products continue to fascinate chemists and biologists due to their exceptionally large and complex molecular architectures and potent and diverse biological activities. Tremendous progress has been made over the past decade toward the total synthesis of marine polycyclic ether natural products. In this area, a convergent strategy for assembling small fragments into an entire molecule always plays a key role in successful total synthesis. This review describes our efforts to develop convergent strategies for the synthesis of polycyclic ethers and their application to the total synthesis of gambierol, gymnocin-A, and brevenal, and to the partial synthesis of the central part of ciguatoxins and the nonacyclic polyether skeleton of gambieric acids.

Abstract
Among nature's ecosystems, the marine environment has been an extremely rich source of structurally complex and biologically active molecules. This review aims to cover the recent developments in the synthesis of marine natural products, also reflecting the trend of their increased use to address biological questions. The examples chosen should be viewed as representative of the different structural motifs on the one hand and the strategies and stimuli for their synthesis on the other.

Abstract
The first total synthesis of gymnocin-A (1), a cytotoxic polycyclic ether isolated from a notorious red tide dinoflagellate, Karenia mikimotoi, has been accomplished. The synthesis relies heavily on the Suzuki-Miyaura cross-coupling-based methodology to assemble the tetradecacyclic polyether skeleton. Convergent union of the GHI (5) and KLMN (6) rings, both of which were prepared from a common intermediate 7, and the subsequent ring closure of the J ring delivered the GHIJKLMN ring. The crucial coupling between the ABCD and FGHIJKLMN ring fragments (3 and 4, respectively) and stereoselective installation of the C17 hydroxyl group, followed by cyclization of the E ring gave rise to the tetradecacyclic polyether skeleton 2. Finally, incorporation of the 2-methyl-2-butenal side chain completed the total synthesis of gymnocin-A. The convergent nature of the synthesis, which employs three fragments of comparable complexity, is well-suited for preparation of various structural analogues of gymnocin-A to explore the structure-activity relationship. The results of preliminary structure-activity relationship studies of several synthetic analogues are also provided.

Abstract
The first total synthesis of (-)-gambierol (1), a marine polycyclic ether toxin, has been achieved. Key features of the successful synthesis include (1) a convergent union of the ABC and EFGH ring fragments (5 and 6, respectively) via our developed B-alkyl Suzuki-Miyaura cross-coupling strategy leading to the octacyclic polyether core 4 and (2) a late-stage introduction of the sensitive triene side chain by use of Pd(PPh(3))(4)/CuCl/LiCl-promoted Stille coupling. The ABC ring fragment 5 was synthesized in a linear manner (B --> AB --> ABC), wherein the A ring was formed by intramolecular hetero-Michael reaction and the C ring was constructed via 6-endo cyclization of hydroxy epoxide 7. An improved synthetic entry to the EFGH ring fragment 6 is also described, in which SmI(2)-induced reductive cyclization methodology was applied to the stereoselective construction of the F and H rings, leading to 6 with remarkable overall efficiency. Stereoselective hydroboration of 5 and subsequent Suzuki-Miyaura coupling with 6 provided endocyclic enol ether 45 in high yield, which was then converted to octacyclic polyether core 4. Careful choice of the global deprotection stage was a key element for the successful total synthesis. Functionalization of the H ring and global desilylation gave (Z)-vinyl bromide 2. Finally, cross-coupling of 2 with (Z)-vinyl stannane 3 under Corey's Pd(PPh(3))(4)/CuCl/LiCl-promoted Stille conditions completed the total synthesis of (-)-gambierol (1).

Abstract
[structure: see text] Ciguatoxin CTX3C is a representative congener of ciguatoxins, which are known to be the principal causative agents of ciguatera seafood poisoning. The structure of CTX3C spans more than 3 nm and is characterized by 13 ether rings. In this paper, an improved total synthesis of CTX3C is reported. Alteration of the protective group from benzyl ether to 2-naphthylmethyl (NAP) ether drastically increases the yield for final global deprotection and has provided a sufficient amount of sample for further biological studies.

Abstract
A novel protocol for assembling polycyclic ethers was developed and successfully applied to the synthesis of the EFGH ring system of ciguatoxin CTX3C. A key transformation involves construction of an O,S-acetal through coupling of alpha-chlorosulfide and a secondary alcohol under mild conditions. The method is highly applicable to use with sensitive substrates and will enable the synthesis of various natural and artificial polycyclic ethers. [reaction: see text]

Abstract
The development of new reactions that facilitate the creative and efficient synthesis of molecular structures with desirable properties continues to fascinate chemists. The test of a significant contribution is its acceptance over time by the scientific community. The B-alkyl Suzuki-Miyaura cross-coupling reaction appears to be one such reaction. Since its disclosure by Suzuki and Miyaura in 1986, this reaction has been an attractive solution to challenging synthetic problems.

Abstract
More than 20,000 people suffer annually from ciguatera seafood poisoning in subtropical and tropical regions. The extremely low content of the causative neurotoxins, designated as ciguatoxins, in fish has hampered the isolation, detailed biological studies, and preparation of anti-ciguatoxin antibodies for detecting these toxins. The large (3 nanometers long) and complicated molecular structure of ciguatoxins has impeded chemists from completing their total synthesis. Our highly convergent strategic approach featuring the chemoselective ring-closing metathesis reaction as a key tactic has enabled the total synthesis of ciguatoxin CTX3C, which will provide a practical supply for further studies.

Abstract
[structure: see text]. A convergent synthetic route to the octacyclic polyether core of gambierol, a marine polycyclic ether toxin, has been developed. The synthesis involves construction of two fragments representing the ABC and EFGH ring systems followed by their coupling via a B-alkyl Suzuki reaction.
