Polynuclear copper(ii) pyrazolate complexes: Temperature-dependent protonolysis reactions, crystal structures and high catalytic activity toward the condensation of nitriles with 2-aminoalcohol

Reaction of Cu(OAc)2·H2O and 1H-pyrazole-3,5-dicarboxylic acid dimethyl ester (Hdcmpz) in MeOH at room temperature afforded one tetranuclear Cu(ii)/pyrazolate complex [{Cu 2(μ-OAc)2}2(μ-dcmpz)2/

Rhodium(III)-Catalyzed Oxidative Cyclization of Oxazolines with Cyclopropanols: Synthesis of Isoindolinones

The synthesis of C3-substituted isoindolin-1-ones from oxazolines and cyclopropanols has been achieved with oxazoline as a bifunctional nucleophilic directing group. The reaction proceeds by the cleavage of three chemical bonds and allows the formation of three new chemical bonds, a C-N bond, a C-C bond, and a C-O bond, in a single step.

Oxazolinyl-Assisted Ru(II)-Catalyzed C-H Allylation with Allyl Alcohols and Synthesis of 4-Methyleneisochroman-1-ones

We report herein a ruthenium-catalyzed, oxazoline-directed strategy for C-H allylation of aryl oxazolines using allylic alcohols as the coupling partner. The present transformation unravels the unusual reactivity of allylic alcohols in the synthesis of 4-

Cu(II) immobilized on Fe3O4@Agarose nanomagnetic catalyst functionalized with ethanolamine phosphate–salicylaldehyde schiff base: A magnetically reusable nanocatalyst for preparation of 2-substituted imidazolines, oxazolines, and thiazolines

Herein we synthesized Cu(II) immobilized on Fe 3 O 4 @Agarose functionalized with ethanolamine phosphate–salicylaldehyde Schiff base (Fe 3 O 4 @Agarose/SAEPH 2 /Cu(II)) as a new and cost-effective nanomagnetic catalyst. The nanomagnetic catalyst was characterized by FT- IR, XRD, VSM, SEM- EDX, TEM, TGA, and ICP techniques and it was found that the particles were about 9–25 nm in size and spherical with entrapment of the Fe 3 O 4 particles in the hollow pore structure of the agarose. The prepared nanomagnetic catalyst showed excellent activity for preparation of 2-substituted imidazolines, oxazolines, and thiazolines. The catalyst is easy to prepare and exhibits higher catalytic activity than some commercially available copper sources. More importantly, this nanomagnetic catalyst can be easily recovered by using a permanent magnet and reused for at least seven cycles without significant deactivation.

Highly efficient synthesis of β-nitrate ester carboxamides through the ring-opening of 2-oxazolines

A novel method for the synthesis of β-nitrate ester carboxamides using non-corrosive tert-butyl nitrite (TBN) as the nitro source and easily available oxygen as the oxidant has been developed. Variously substituted 2-oxazolines were efficiently ring-opened to deliver the corresponding products in excellent yields. Notably, this reaction provides fast access to pharmaceuticals such as nicorandil.

A Mild and Regioselective Route to Functionalized Quinazolines

A Rh-catalyzed ortho-amidation cyclocondensation sequence gave a range of 4-aminoquinazolines in high yield. The method features a remarkably mild C(sp2)-H activation step and can be exploited to rapidly access compounds with established biological activity.

A convenient synthesis of 2-oxazolines and 2-benoxazoles with PPh3-DDQ as the dehydrating reagent

2-Oxazolines and 2-benoxazoles were synthesized in high yields from acylamino alcohols and acylaminophenols, respectively, with triphenylphosphine- 2,3-dichloro-5,6-dicyanobenzoquinone (PPh3-DDQ) as the dehydrating and activating reagent. The synthesis was accomplished under neutral conditions.

METHOD FOR PRODUCING 2-OXAZOLINE ANALOGUE OR 1,3-OXAZINE ANALOGUE

The present invention is a method for producing a 2-oxazoline analogue or a 1,3-oxazine analogue represented by the following general formula (3) by reacting a 1,2-aminoalcohol compound or a 1,2-aminothiol compound with an α,α-dihaloamine compound. (In the formula, n represents 0 or 1, and R represents an oxygen atom or a sulfur atom. R1, R2 and R3 each represents an atom or a group shown in Group 1 to Group 3, and R° represents an atom or a group shown in Group 2 or Group 3. Two or more of R1, R2 and R3 may be bonded to each other to form a ring. Group 1: a hydrogen atom, a halogen atom, a nitro group, a cyano group, a formyl group, a carboxyl group, a sulfonyl group, a sulfinoyl group or a sulfenyl group; Group 2: an alkyl group, which may have an arbitrary substituent, an aryl group or an aralkyl group; and Group 3: an alkyl-substituted, aryl-substituted or aralkyl-substituted oxy group, a carbonyl group, an oxycarbonyl group, a carbonyloxy group, a thio group, a sulfonyl group, a sulfinoyl group or a sulfenyl group)

A facile synthesis of oxazolines, thiazolines, and imidazolines using α,α-difluoroalkylamines

β-Amino alcohols, β-amino thiols, and β-diamines can be converted to the corresponding oxazoline, thiazoline, and imidazoline derivatives, respectively, by reaction with α,α-difluoroalkylamines under mild conditions. The reaction is applicable for the synthesis of optically active heterocyclic compounds. Georg Thieme Verlag Stuttgart.

A convenient synthesis of oxazolines and imidazolines from aromatic aldehydes with pyridinium hydrobromide perbromide in water

Various 2-oxazolines were prepared from aromatic aldehydes and 2-aminoethanol with pyridinium hydrobromide perbromide in water at room temperature. 2-Imidazolines were also obtained in good yields from aromatic aldehydes and ethylenediamine under the same reaction conditions.
