Abstract
The addition of a lithium anion of diphenylallylimine to nonracemic sulfinimines was investigated. It was found that the reaction with sulfinimines derived from aliphatic aldehydes afforded the products with excellent diastereoselectivity (>99:1), furnishing the product vicinal diamines in very good yields. Application of the formed product vicinal diamines was demonstrated in the total synthesis of the natural product (-)-epiquinamide.

Abstract
The autoxidative condensation of 2-aryl-2-lithio-1,3-dithianes is here reported. Treatment of 2-aryl-1,3-dithianes with n-BuLi in the absence of any electrophile leads to condensation of three molecules of 1,3-dithianes and formation of highly functionalized α-thioether ketones orthothioesters in 51-89% yields upon air exposure. The method was further expanded to benzaldehyde dithioacetals, affording corresponding orthothioesters and α-thioether ketones in 48-97% yields. The experimental results combined with density functional theory studies support a mechanism triggered by the autoxidation of 2-aryl-2-lithio-1,3-dithianes to yield a highly reactive thioester that undergoes condensation with two other molecules of 2-aryl-2-lithio-1,3-dithiane.

Abstract
In this paper, we report a full account of the synthesis of dimeric hexahydropyrroloindole alkaloids and its analogues. The key feature of our new strategy is the novel catalytic copper (10 %) mediated intramolecular arylations of o-haloanilides followed by intermolecular oxidative dimerization of the resulting oxindoles in one pot. This sequential reaction leads to the key intermediates for the synthesis of (+)-chimonanthine, (+)-folicanthine, (-)-calycanthine and (-)-ditryptophenaline. In the presence of catalytic amount of cuprous iodide (10 %), an intramolecular arylation of o-haloanilides followed by an intermolecular oxidative dimerization of the resulting oxindoles leads to a common intermediate for the synthesis of (+)-chimonanthine, (+)-folicanthine and (-)-calycanthine. Based on this cascade sequence, we also developed a flexible strategy towards the asymmetric syntheses of dimeric HPI alkaloids (-)-ditryptophenaline and its analogues.

Abstract
Several aza-C-pseudonucleosides bearing 1,3-benzothiazin-4-one (6 and 7) were prepared by the one-pot three-component condensation from the iminosugar aldehyde 3, amino acid ethyl/methyl ester hydrochlorides 4(a-c), and 2-mercaptobenzoic acid 5. After removal of Boc and the isopropylidene groups, the target novel tetracyclic iminosugars fused benzo[e][1,3]thiazin-4-one 1(a-c) and 2(a-b) were first afforded by the intramolecular cyclo-amidation reaction. Their structures were determined by their (1)H, (13)C NMR, and HRMS (ESI) spectra and X-ray. The tetracyclic iminosugars 1(a-c) and 2(a-b) were examined for their HIV reverse transcriptase (RT) inhibitory activities. The result showed that all compounds could effectively inhibit RT activity. Among them, compound 2a was the best one with the IC50 value of RT inhibitory activity of 0.82μM. Structure-activity relationship analysis suggested that 1'R configuration in the tetracyclic azasugars was of benefit to their anti-HIV RT activity.

Abstract
This review of simple indolizidine and quinolizidine alkaloids (i.e., those in which the parent bicyclic systems are in general not embedded in polycyclic arrays) is an update of the previous coverage in Volume 55 of this series (2001). The present survey covers the literature from mid-1999 to the end of 2013; and in addition to aspects of the isolation, characterization, and biological activity of the alkaloids, much emphasis is placed on their total synthesis. A brief introduction to the topic is followed by an overview of relevant alkaloids from fungal and microbial sources, among them slaframine, cyclizidine, Steptomyces metabolites, and the pantocins. The important iminosugar alkaloids lentiginosine, steviamine, swainsonine, castanospermine, and related hydroxyindolizidines are dealt with in the subsequent section. The fourth and fifth sections cover metabolites from terrestrial plants. Pertinent plant alkaloids bearing alkyl, functionalized alkyl or alkenyl substituents include dendroprimine, anibamine, simple alkaloids belonging to the genera Prosopis, Elaeocarpus, Lycopodium, and Poranthera, and bicyclic alkaloids of the lupin family. Plant alkaloids bearing aryl or heteroaryl substituents include ipalbidine and analogs, secophenanthroindolizidine and secophenanthroquinolizidine alkaloids (among them septicine, julandine, and analogs), ficuseptine, lasubines, and other simple quinolizidines of the Lythraceae, the simple furyl-substituted Nuphar alkaloids, and a mixed quinolizidine-quinazoline alkaloid. The penultimate section of the review deals with the sizable group of simple indolizidine and quinolizidine alkaloids isolated from, or detected in, ants, mites, and terrestrial amphibians, and includes an overview of the "dietary hypothesis" for the origin of the amphibian metabolites. The final section surveys relevant alkaloids from marine sources, and includes clathryimines and analogs, stellettamides, the clavepictines and pictamine, and bis(quinolizidine) alkaloids.

Abstract
A unified synthetic strategy to the Cryptocarya family of natural products has been achieved employing four-component fragment unions in a "single flask" exploiting Anion Relay Chemistry (ARC). Functionalization of the ARC adducts permits rapid construction of five polyhydroxylated di- and tetrahydropyrone natural products of the Cryptocarya class (1-5), in a total of 7-9 steps from commercially available materials.

Abstract
We report, for the first time, the synthesis of 8-aza-analogues of PGE2. The SmI2-mediated cross coupling reactions of γ-lactam-hemiaminal 9, lactam 2-pyridyl sulfide 17, and lactam 2-pyridyl sulfone 18 with activated alkenes/alkyne were first developed, giving the corresponding γ-lactams in 49-78%, 45-75%, and 75-90%, respectively. The reactions of lactam 2-pyridyl sulfide and 2-pyridyl sulfone proceeded with ≥12:1 trans-diastereoselectivities. This represents the first intermolecular coupling reaction of the γ-lactam N-α-alkyl radicals of types B, B1, and B2 with activated alkenes. Two radical-based mechanisms were suggested. The asymmetric synthesis of the 11-hydroxylated analogue of the highly selective EP4 receptor agonist PF-04475270 (30), the 11-hydroxylated analogue of ocular hypotensive CP-734432 (31), compounds 35 and 36 have been achieved on the basis of this method.
