Synthesis of the enantiomers of the dual function 2-nitroimidazole radiation sensitizer RB 6145

Short, efficient pathways are described for the synthesis of racemic 2-nitroimidazole radiation sensitizer RB-6145 (2a) and each of its corresponding (R)- and (S)-enantiomers (2b and 2c, respectively). The synthesis of each enantiomer commences with the appropriate chiral epichlorohydrin and utilizes a novel application of 3-trimethylsilyl-2-oxazolidinone (3b) as a mild, safe surrogate for highly toxic aziridine. The synthesis of the (R)-enantiomer (2b) has been successfully scaled up to provide multi-kilo quantities of material for early stage preclinical evaluation.

Total synthesis of elisabethin A: Intramolecular Diels-Alder reaction under biomimetic conditions

We describe the first total synthesis of the marine diterpenoid elisabethin A. The synthesis uses (S)-hydroxy-2-methyl-propionate as the chiral starting material, which is elaborated into a dienyl-iodide and added to an aryl acetic acid ester via enolate alkylation. The hydroquinoid system is oxidized to the quinone which serves as the dienophile in a highly stereocontrolled intramolecular Diels-Alder addition. This IMDA reaction, which to our knowledge is the first one to employ a terminal (Z)-diene, proceeds under biomimetic conditions (water, ferrichloride as the oxidant, room temperature) with high yield and stereoselectivity. The Diels-Alder adduct is transformed into the natural product via a three-step sequence including selective hydrogenation, base-catalyzed epimerization of the cis- into the trans-decalin system and O-demethylation.

Addition to activated imines of enolates from chiral N-acyloxazolidinones

The lithium and titanium enolates of N-acyloxazolidinones 1a-c add in their chelated forms to PhCH=NTs, to give stereoselectively the beta-amino acid derivatives 3a-c and 4a-c. The relative configurations of the newly created chiral centres were established by conversion to the trans (8a-c) or cis (9a, c) beta-lactams. Absolute stereochemistry was assigned by correlation with known compounds 10a and ent-11a, together with an X-ray crystal structure determination on 9a. The use of the lithium enolate of 1a at -78C gave only a 1.4:1 ratio of anti product 3a to syn product 4a, but this ratio was improved to >5:1 by the use of the chlorotitanium enolate of 1a at-55C or below. Similar results were obtained by using the chlorotitanium enolate of 1b, but for the chlorotitanium enolate of the N-(phenylacetyl)oxazolidinone 1c the proportion of syn product 4c to anti product was significantly greater, consistent with a kinetically controlled reaction involving the si face of the chelated (Z)-enolate and the competing alternative transition states TS3 (reaction on si face of imine) and TS7 (reaction on re face of imine).

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Product Details of 16251-45-9, you can also check out more blogs about16251-45-9

Design and synthesis of an orally active macrocyclic neutral endopeptidase 24.11 inhibitor

A potent macrocyclic inhibitor of neutral endopeptidase (NEP) 24.11 was designed using a computer model of the active site of thermolysin. This 10- membered ring lactam represents a general mimic for any hydrophobic dipeptide in which the two amino acid side chains bind to an enzyme in a contiguous orientation. The parent 10-membered ring lactam was synthesized and exhibited excellent potency as an NEP 24.11 inhibitor (IC50 = 3 nM). In order to improve oral bioavailability, various functionality was attached to the macrocycle. These modifications lead to CGS 25155, an orally active NEP 24.11 inhibitor that slows down the degradation of the cardiac hormone atrial natriuretic factor, producing a lowering of blood pressure in the DOCA-salt rat model of hypertension.

Reactions of secondary propargylamines with heteroallenes for the synthesis of diverse heterocycles

This focused review aims to summarize recent developments in the processes involving additions of secondary propargylamines to various heteroallenes and subsequent transition metal-catalyzed or electrophile-mediated cyclizations. The utility of this convenient and tunable strategy spans from the carbon dioxide fixation and target-oriented synthesis of complex natural and biologically active products to the generation of extended synthetic libraries of diverse oxygen-, nitrogen- and sulfur-containing heterocycles. For comparative purposes, the analogous transformations of propargylic alcohols are also highlighted in this account.
