NMO⋅TPB: a selectivity variation on the Ley-Griffith TPAP oxidation.
A non-hygroscopic tetraphenylborate salt of N-methylmorpholine-N-oxide (NMO) is reported (NMO⋅TPB), which modulates the standard Ley-Griffith oxidation such that benzylic and allylic alcohols are oxidised selectively. An attractive feature of this new protocol is that anhydrous conditions are not required for this selective tetra-n-propylammonium perruthenate (TPAP) oxidation, superseding the r...
متن کاملElucidating the mechanism of the Ley–Griffith (TPAP) alcohol oxidation† †Electronic supplementary information (ESI) available. See DOI: 10.1039/c7sc04260d
The Ley-Griffith reaction is utilized extensively in the selective oxidation of alcohols to aldehydes or ketones. The central catalyst is commercially available tetra-n-propylammonium perruthenate (TPAP, n-Pr4N[RuO4]) which is used in combination with the co-oxidant N-methylmorpholine N-oxide (NMO). Although this reaction has been employed for more than 30 years, the mechanism remains unknown. ...
متن کاملTotal synthesis of dictyodendrin B.
A concise total synthesis of dictyodendrin B (1) is reported, a scarce marine alkaloid endowed with promising telomerase inhibitory activity. Key steps of the chosen route are a reductive cyclization of ketoamide 11 to indole 12 mediated by low-valent titanium (from TiCl3 and KC8) followed by a photochemical 6pi-electrocyclization, which was performed in the presence of Pd/C and nitrobenzene to...
متن کامل1,4,5,8-Tetra-n-butylanthracene
The mol-ecule of the title compound, C(30)H(42), occupies a special position on an inversion center. The four butyl side chains have all-trans planar conformations, and the alkyl planes are nearly orthogonal to the anthracene plane [C-C-C-C torsion angles of 79.6 (2) and 78.2 (2)°]. The overall mol-ecule has a stair-like shape with the n-butyl groups at the 1 and 8 positions extending towards t...
متن کاملTetra-n-propylammonium chloride monohydrate
The crystal structure of the title salt hydrate, C(12)H(28)N(+)·Cl(-)·H(2)O, consists of non-inter-acting cations and anions. The water mol-ecule forms hydrogen bonds to two chloride ions, about a center of inversion, generating a planar eight-membered {⋯H-O-H⋯Cl}(2) ring.
