Amorphous nickel powder (Ni(0)) was utilised as a catalyst under mild, aqueous, basic conditions for enhancing the sodium borohydride-mediated reduction of C-N multiple bonds such as oximes, imines,… (More)
A novel and efficient [3+2] cycloaddition reaction of azaoxyallyl cations and 1,2-benzisoxazoles to give oxazoline derivatives has been developed. The transformation provides a rapid entry to… (More)
In order to perform a transfer process of the porphyrin moiety across membrane media, an amphiphilic porphyrin 5,10,15-tri(4-hydroxyphenyl)-20-(4-hexadecyloxy-phenyl) porphyrin (P1) and its… (More)
Total synthesis of Spirobacillene A (VI) is accomplished in 6 steps whereas for Spirobacillene B (VIII) 4 reaction steps are required.
The novel title synthesis enables the efficient access of two types of aza- heterocycles, 2,3-dihydropyrroles and 2,5-dihydroazepines, through formal aza-[3 + 2] and [4 + 3] cycloadditions from… (More)
A wide variety of oximes, imines, hydrazones and nitriles is efficiently reduced to the corresponding amines using sodium borohydride in the presence of amorphous nickel as catalyst.
A novel dynamic covalent gel strategy is reported to immobilize an asymmetric catalyst within the channels of a microfluidic flow reactor. A layer of a catalytically active Mn-salen dynamic covalent… (More)
