Abstract
The naturally occurring (4R,5R)-4-hydroxy-γ-decalactone from the Japanese orange fly and the antipode of (4S,5R)-4-hydroxy-γ-dodecalactone from the harvestmen arachnid and their stereoisomers are synthesized from the chiral pool material d-glucono-δ-lactone in a few steps. The one-pot conversion of the latter to γ-vinyl-β-hydroxy-γ-lactone, cross-metathesis with requisite olefin, and hydrogenation enabled the synthesis of syn-lactones in just a two-pot operation. An additional efficient Pd-catalyzed allylic isomerization of γ-vinyl-β-hydroxy-γ-lactone led to the anti-lactones in high yields.

Abstract
A short, convergent and general strategy for stereoselective total synthesis of biologically active α-substituted γ-hydroxymethyl γ-lactone based natural products cananginone C and debilisone A has been developed. The salient features of this synthesis include Cadiot-Chodkiewicz coupling, Evans allylation, Sharpless asymmetric dihydroxylation and γ-lactonization. The originally proposed structure of debilisone A has been revised.

Abstract
Among the different types of diazocarbonyl substrates found in the literature to date, α,β-unsaturated diazoketones have proven to be very promising as multifunctional intermediates. Possessing a diazo group, a ketone function and a double bond all together in a single molecule, these compounds constitute versatile building blocks for synthesis. For example, double bond functionalization, followed by intramolecular insertion reactions, can be a short alternative to prepare several rings or heterocyclic compounds. Although there are many efficient methods to prepare diazoketones, very few can be extended to the synthesis of the a,β-unsaturated diazoketones; this is likely responsible for their limited application in synthesis. Unfortunately, the classical methods to prepare saturated- or aryl-diazoketones (acylation of diazomethane with acyl chlorides or mixed anhydrides) are not suitable for preparing a,β-unsaturated diazoketones, since pyrazolines (dipolar cycloaddition products from the reaction between diazomethane and the double bond) are formed. Although Danheiser's two-step detrifluoroacetylative procedure (starting from a,β-unsaturated methyl ketones) is considered the best general method, it cannot be applied to the synthesis of all types of a,β-unsaturated diazoketones. For example, the synthesis of more complex unsaturated diazoketones, as well as those with epimerizable stereocenters in the γ position, was never described before. Another point is related to the geometry of the double bond, since practically all examples described thus far refer to unsaturated diazoketones with E geometry. In recent years, our research group developed two new Horner-Wadsworth-Emmons reagents (containing a diazocarbonyl function) that could be easily applied in the one-step preparation of α,β-unsaturated diazoketones from aldehydes. Not only were we able to selectively synthesize E- and Z-unsaturated diazoketones, but also to employ these useful platforms in the short synthesis of several nitrogen heterocycles such as indolizidines, quinolizidines, piperidines, and pyrrolidines. Our purpose in this Account is to introduce this class of diazoketone and provide a brief historical overview, culminating in how we developed a general methodology to prepare them. In continuation, we wish to call of the reader's attention to these important building blocks, showing how we could apply them to the synthesis of several nitrogen heterocycles, including the very short preparation of some popular alkaloids. The reader will also notice that the combination of these three important functions in the same molecule makes these compounds special as well as provides powerful platforms to access many important molecules in a direct fashion.

The first synthesis of gracilioether F, a polyketide natural product with an unusual tricyclic core and five contiguous stereocenters, is described. Key steps of the synthesis include a Lewis acid promoted ketene-alkene [2+2] cycloaddition and a late-stage carboxylic acid directed C(sp(3) )H oxidation. The synthesis requires only eight steps from norbornadiene.

Abstract
The total syntheses of basiliolide C and previously unreported epi-basiliolide C are achieved by an Ireland-Claisen/Diels-Alder cascade. The development of a palladium catalyzed cross-coupling of methoxy alkynyl zinc reagents allows for the protecting-group-free syntheses of transtaganolides C and D. Syntheses of transtaganolides C and D are accomplished in a single operation to generate three rings, two all-carbon quaternary centers, and four tertiary stereocenters from a monocyclic, achiral precursor.

Abstract
An efficient synthesis of olefins by the coupling of stabilized, semistabilized, and nonstabilized phosphorus ylides with various carbonyl compounds in the presence of silver carbonate is reported. Wittig olefination of aromatic, heteroaromatic, and aliphatic aldehydes (yields >63%) and a ketone (yield 42%) are demonstrated. These reactions proceed overnight at room temperature, under weakly basic conditions, and as such extend the applicability of the Wittig reaction to base-sensitive reactants.

Abstract
An unprecedented enantioselective and general olefin isomerization was realized via biomimetic proton transfer catalysis with a new chiral organic catalyst. A broad range of mono- and disubstituted β,γ-unsaturated butenolides were transformed into the corresponding chiral α,β-unsaturated butenolides in high enantioselectivity and yield in the presence of as low as 0.5 mol % catalyst. Mechanistic studies have revealed the protonation as the rate-determining step.

Abstract
New chlorodiols (±)-3 and (±)-5 are densely functionalized and versatile synthons. They are converted in one step on a gram scale into 2-chlorolactones (±)-6 and (±)-7 and into 4-hydroxy glycidate esters (±)-9 and (±)-10. The 4-hydroxy glycidate esters (±)-9 and (±)-10 are converted stereospecifically and regiospecifically into oxazolines (±)-13 and (±)-14 and into cyclic carbamates (±)-18-(±)-20. The 4-hydroxy glycidate ester (±)-10 undergoes stereocontrolled and regiocontrolled epoxide opening by sodium azide to form the 2-azido-3,4-dihydroxy alkanoate (±)-21. Finally, chlorodiol (±)-5 reacts stereospecifically with silver triflate to form the 2,3-dihydroxyfuranone (±)-26.

Abstract
The bicyclic triaminophosphine P(RNCH(2)CH(2))(3)N (R = i-Bu, 1c) serves as an effective promoter for the room-temperature stereoselective synthesis of α,β-unsaturated esters, fluorides, and nitriles from a wide array of aromatic, aliphatic, heterocyclic, and cyclic aldehydes and ketones, using a range of Wadsworth-Emmons (WE) phosphonates. Among the analogues of 1c [R = Me (1a), i-Pr (1b), Bn (1d)], 1a and 1b performed well, although longer reaction times were involved, and 1d led to poorer yields than 1c. Functionalities such as cyano, chloro, bromo, methoxy, amino, ester, and nitro were well tolerated. We were able to isolate and characterize (by X-ray means; see above) the reactive WE intermediate species formed from 2b and 1c.
