AZINOTHRICIN SYNTHETIC STUDIES. 1. EFFICIENT ASYMMETRIC SNTHESES OF (3R)- AND (3S)-PIPERAZIC ACIDS

A convenient asymmetric synthesis of both (3R)-and (3S)-piperazic acids has been developed that is based on electrophilic hydrazination of a chiral bromovaleryl carboximide enolate with di-tert-butyl azodicarboxylate, followed by subsequent intramolecular SN2 displacement of the bromide by the resulting aza anion.The diastereoselectivity of the process is typically greater than 96percent.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Formula: C10H11NO2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 102029-44-7, in my other articles.

Total synthesis of (-)-exiguolide

The first total synthesis of the naturally occurring enantiomer of exiguolide ((-)-1) has been completed. This very convergent synthesis features the following as main steps: (I) a Trost’s ruthenium-catalyzed ene-yne cross-coupling reaction (this complex transformation allows the challenging control of the C5-C28 double bond geometry along with the stereoselective construction of the tetrahydropyran ring A) and (II) a very efficient one-pot, two-step stereoselective conjugated allyllc alcohol substitution that allowed the control of the C15 stereogenic center.

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

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.
