Abstract
We report a copper-catalyzed reductive aldol addition to aldehydes and ketones, with pinacolborane as stoichiometric reductant, that results in the generation of stereodefined syn-aldol products. Cyclic, acyclic, fused and spirocyclic aldols bearing contiguous stereocenters are obtained with excellent yields and diastereoselectivities. Moreover, enantioselective reactions could be carried out with cycloalkenones to deliver aldols bearing three contiguous stereocenters and with up to 98 % ee. Computations reveal that the enolborate intermediate undergoes the syn-aldol reaction via a twist-boat transition state that is stabilized by non-classical hydrogen bonding interactions.

Abstract
The [5-7-6-3] tetracyclic core of premyrsinane diterpenes was convergently synthesized via the stereoselective three-component coupling of a 2-propenyl unit, an enone, and an aldehyde, followed by the relay ring-closing metathesis with conformation control of the substrate to construct the 7-membered ring.

Abstract
A short synthesis of the postulated structure for indolizidine alkaloid 259B with the hydrogens at C5 and C9 entgegen has been achieved with complete control of stereochemistry at C5. Both diastereoisomers at C8 were obtained, but neither proved to be the natural product. The comparison of the mass and FTIR spectral properties of the synthetic compounds to those of the natural material strongly suggest that the gross structure is correct and that the difference may be a branch in the C5 alkyl side-chain. The GC-retention times of the two synthetic compounds were markedly longer than that of the natural 5,9E-259B.

Abstract
The synthesis and evaluation for anti- and proapoptotic properties of cyclopentenone prostaglandin analogs are described. Novel J-type analogs of NEPP11 with a cross-conjugated cyclopentadienone moiety and a lipophilic omega-side chain suppressed manganese ion-induced apoptosis of PC12 cells at comparable levels to NEPP11, while monoenone derivatives were inactive. The proapoptotic activities of J-type analogs were much lower than that of NEPP11. Natural 15-deoxy-Delta(12,14)-PGJ(2) and Delta(7)-PGA(1) methyl ester were highly toxic, inducing apoptosis at lower concentrations.

Abstract
An efficient solution-phase synthesis of rac-15-deoxy-delta(12,14)-PGJ2 (15dPGJ2) derivatives that contain variable alpha and omega chains based on a polymer-assisted strategy and their neurite-outgrowth-promoting activity are described. The strategy for the synthesis of PGJ2 derivatives involves the use of a vinyl iodide bearing cyclopentenone as a key intermediate, which undergoes Suzuki-Miyaura coupling and subsequent Lewis acid catalyzed aldol condensation for incorporation of the omega and alpha chains, respectively. For easy access to the PGJ2 derivatives, a polymer-supported catalyst and scavengers were adapted for use in these four diverse steps, in which workup and purification can be performed by simple filtration of the solid-supported reagents. By using this methodology, we succeeded in the synthesis of 16 PGJ2 derivatives with four alkyl boranes and four aldehydes. The neurite-outgrowth-promoting activity of the 16 synthetic compounds in PC12 cells revealed that the side-chains play a major role in modulating their biological activity. The carboxylic acid on the alpha chain improved the biological activity, although it was not absolutely required. Furthermore, a PGJ2 derivative with a phenyl moiety on the omega chain was found to exhibit an activity comparable to that of natural 15dPGJ2.

Abstract
The solid-phase synthesis of a combinatorial cross-conjugated dienone library based on the structure of clavulones and their biological activity are reported. Clavulones are a family of marine prostanoids, and are composed of a cross-conjugated dienone system bearing two alkyl side-chains. The cross-conjugated dienone system irreversibly reacted with two nucleophiles. Our strategy for the solid-phase synthesis of the cross-conjugated dienones involves the Sonogashira-coupling reaction of a solid-supported cyclopentenone 10 bearing an acetylene group, followed by aldol condensation with aldehydes. The diphenyl derivative 7 aA was prepared from the solid-supported cyclopentenone 10 in 56% total yield. Combinatorial synthesis of a small library using twelve halides and eight aldehydes resulted in the production of 74 desired compounds from 98 candidates, and were detected by their mass spectra. Antiproliferative effects of the crude compounds against HeLaS3 cells showed that eleven samples showed strong antitumor activity (IC50<0.05 microM). Further biological examination of four purified compounds by using five tumor cell lines (A549, HeLaS3, MCF7, TMF1, and P388) revealed strong cytotoxicity comparable to that of adriamycin.

[reaction: see text]. Enantiomerically enriched 2,3-disubstituted cyclopentanones were prepared via copper-catalyzed 1,4-reduction of 3-substituted cyclopentenones followed by alkylation of the resulting silyl enol ether. Using this procedure, trans-2,3-disubstituted cyclopentanones were produced in moderate to good overall yields (42-67%) and with excellent enantiomeric and diastereomeric excesses. The reduction and alkylation were performed in a single reaction vessel.
