Abstract:

A new methodology for the synthesis of substituted carboxylic acids is described. Alkylation of either ethyl (benzothiazol-2-ylsulfonyl)acetate or ethyl 2-(benzothiazol-2-ylsulfonyl)propionate was achieved with alkyl halides and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in dichloromethane solution. These products were then desulfinated and hydrolysed in one-pot under mild conditions to give substituted acetic acids in good-to-excellent yields.

New type of amide conjugates of steroid and bile acids with D-glucosamine 1 and 2 were prepared. Title compounds are prepared via acid chloride or using N-[({[(1E)-1-cyano-2-ethoxy-2-oxoethylidene]amino}oxy)(dimethylamino)methylidene]-N-methylmethanaminium tetrafluoroborate as condensation agent. They were examined for gelation properties with negative results. Per-O-acetylated D-glucosamine hydrochloride was prepared in one step procedure from D-glucosamine hydrochloride by acetylation in a mixture of acetyl chloride and acetic acid.

Abstract:

Through N-acylation of a- or b-amino acid units by 2-(3-oxo-2,3-dihydro-1H-inden-5-yloxy)acetic acid using the method of N-hydroxysuccinimide esters new dipeptide indan-1-one derivatives were obtained. In general, the direct interaction of the acetic carboxyl group of the substrate with the amino group of the a- or b-dipeptide is a more productive strategy than the sequential peptidic condensation of the two amino acids.

Acetic and propionic acids were the principal SCFAs at 1 and 3 months. Successively, the production of iso‐ and n‐butyric, valeric, and caproic acids was established. At 2 years, the absolute amounts of all SCFAs with the exception of n‐valeric acid had reached adult values. However, not all childr

Abstract:

Abstract Matrix acidizing is one of the most effective techniques to restore formation permeability and increase production rate. It is typically performed using different types of treatments, such as mineral acids, organic acids or chelating agents. These stimulation treatments tend to generate pathways known as wormholes through a chemical reaction with target carbonate formations. Bottom hole conditions play an important role in the treatment selection since they influence the reaction rate, wormholes structure and wellbore integrity.

Abstract A cerebral arteriovenous malformation (AVM) is a congenital vascular lesion of the brain composed of a complex tangle of arteries and veins, which are linked by one or more fistulae [1]. Arterial blood is shunted through the AVM directly to the venous system, precluding arterial blood from perfusing adjacent brain structures. The most common presentation of this disease is cerebral hemorrhage secondary to AVM rupture, with an associated mortality of 15% and a morbidity of 50% [1]. One modality to treat this pathology is endovascular embolization. Generally, endovascular embolization s
