The title compound, (E)-3-methyl-6-(3-oxo-3-(3,4,5-trimethoxyphenyl)prop-1-en-1-yl)-2(3H)-benzothiazolone, was synthesized by both an acid- and base-catalyzed aldol condensation of 3-methyl-6-acetyl-2(3H)-benzothiazolone and 3,4,5-trimethoxyacetophen...

5,9,11-Trihydroxy-2,2-dimethyl-10-(3′-methyl-2′-butenyl)-3-(2″-methyl-3″-butenyl)-pyrano[2,3-a]xanthen-12(2H)-one (1) was isolated from the stem bark of Calophyllum pseudomole. The structure of 1 was established by spectroscopic analysis which includ...

Environmentally friendly and straightforward methods for creating biofuels are required to promote biofuel use. Therefore, we present here a convenient and environmentally friendly direct self-aldol reaction of acetaldehyde in 100 mM borate buffer (p...

Chitooligosaccharide with one 2,5-anhydro-d-mannofuranose unit at the reducing end (COSamf) was prepared by nitrous acid depolymerization of chitosan. The reducing-end functionalization of COSamf by reductive amination with octanoic hydrazide in the...

N-[(1E)-(3-Bromophenyl)methylene]-N-(2-piperidin-1-ylethyl)amine Schiff base was prepared in good yield and characterized by the reflux of equivalent amounts of 2-(piperidin-1-yl)ethanamine with 3-bromobenzaldehyde. The structure of the desired Schif...

The compound named in the title was prepared from N1,N4-diphenethylterephthalamide 1. The resulting bis terephthalamide was subjected to an intramolecular α-amidoalkylation reaction with paraformaldehyde in the presence of heterogeneous catalyst TfOH...
