Continuous flow-processing of organometallic reagents using an advanced peristaltic pumping system and the telescoped flow synthesis of (E/Z)-tamoxifen

A new enabling technology for the pumping of organometallic reagents such as n-butyllithium, Grignard reagents, and DIBAL-H is reported, which utilises a newly developed, chemically resistant, peristaltic pumping system. Several representative examples of its use in common transformations using these reagents, including metal-halogen exchange, addition, addition-elimination, conjugate addition, and partial reduction, are reported along with examples of telescoping of the anionic reaction products. This platform allows for truly continuous pumping of these highly reactive substances (and examples are demonstrated over periods of several hours) to generate multigram quantities of products. This work culminates in an approach to the telescoped synthesis of (E/Z)-tamoxifen using continuous-flow organometallic reagent-mediated transformations.

N-Acyliminium ion chemistry and palladium catalysis: A useful combination to obtain bicyclic heterocycles

By using N-acyliminium ion chemistry, several omega-propadienyllactams and a propadienyloxazolidine were prepared from N-acyliminium ion precursors and propargylsilanes. Treatment of these allene containing lactams and oxazolidinone with allyl halides or an allyl carbonate using Pd(II)-salts as the catalyst gave rise to a coupling-cyclization reaction, yielding bicyclic systems in which the allyl moiety is incorporated. With this methodology several substituted pyrrolizinones, an oxazolone and indolizinone were prepared.

Resolution of 5-hydroxymethyl-2-oxazolidinone by preferential crystallization and investigations on the nature of the racemates of some 2-oxazolidinone derivatives

After ascertaining its conglomerate nature by DSC and solid-state IR analyses, 5-hydroxymethyl-2-oxazolidinone 1, whose enantiomers are very important synthons, was efficiently resolved without chiral auxiliaries by preferential crystallization from a supersaturated isopropanolic solution of the racemate, slightly enriched in one enantiomer (3.7% ee). Favourable conditions to the entrainment were defined utilizing the previously constructed ternary phase diagram {(R)-1, (S)-1, 2-propanol}. Furthermore, the investigations were extended to other chiral 2-oxazolidinones with a functionalized methyl at the 5- or 4-position finding that 5-tosyloxymethyl-2-oxazolidinone is a racemic compound, whereas just the corresponding mesylate is a conglomerate as the parent alcohol 1. Interestingly, 4-hydroxymethyl-2-oxazolidinone 4 proved to be a racemic compound in contrast with its positional isomer 1 demonstrating how a relatively fine variation in the molecular structure can unpredictably influence the crystalline nature of the racemate. The X-ray structure determination carried out on (S)-(+)-1, (±)-4 and (R)-(+)-4 enlightened the importance of the hydrogen bond in determining different supramolecular assembling in the two homochiral compounds with respect to the racemic one and allowed a correlation with the stability of the crystal to be made.

Carboxylation and Mitsunobu reaction of amines to give carbamates: Retention vs inversion of configuration is substituent-dependent

(Equation Presented) A mild method for the synthesis of carbamates from amino alcohols involves sequential carboxylation with carbon dioxide, followed by a Mitsunobu reaction. Unexpectedly, the stereochemical course of the Mitsunobu reaction is dependent on whether the carbamic acid intermediate is N-substituted with hydrogen (retention) or carbon (inversion).

Regio- and stereoselective synthesis of 1,4-dihydropyridines by way of an intramolecular interaction of a thiocarbonyl or carbonyl with a pyridinium nucleus

Chiral 1,4-dihydropyridines were prepared by the regio- and stereoselective addition of ketene silyl acetals and organometallic reagents to pyridinium salts. In the addition reaction, an intramolecular interaction between the thiocarbonyl or carbonyl with the pyridinium nucleus plays an important role in bringing about the selectivities. The absolute configuration of the newly produced stereogenic center of the 1,4-dihydropyridines was determined by X-ray analysis and CD Cotton effects after conversion into the appropriate derivatives. The working model for the stereoselectivity was proposed based on the ab initio calculations at the RHF/3-21G* level.
