Anilines were protected as 2-(phenylseleno)ethanesulfonanilide (SeES anilide) via sulfonylation by 2-chlorosulfonyl chloride followed by the conjugate addition of benzeneselenol. The SeES anilide was deprotected by radical reduction using tributyltin

The reaction constant (ρ) from the kinetics for hydride transfer from a carbanion (XH–) to 9-arylxanthylium ions (9-GPhXn+) in CH3CN was unusually negative. Thermodynamic analysis indicated that ρ for the simple hydride transfers (only involved w

The course of the reaction of 2-propargyl-2-(2-carboethoxyvinyl)cyclohexanone with tributyltin hydride and AIBN either neat or in benzene solution is discussed. The structure of the spirocyclic major product is shown to differ from that previously su

The reaction of tetrapropylporphycenatocobalt(III) with tributyltin hydride generates a cobalt(III)–hydride porphycene detectable by UV-vis spectroscopy under diluted conditions, whereas it is impossible to characterize hydride species of cobalt po

A series of benzo-fused tricyclic β-lactams, most of them phosphonobenzocarbacephems, were prepared in a straightforward way starting from phosphonoazadienes. In this paper, the synthetic route including a Staudinger reaction towards the β-lactams,

An efficient and practical route for the large-scale synthesis of 2-deoxy-L-erythro-pentose (2-deoxy-L-ribose) starting from L-arabinose was developed using Barton-type free-radical deoxygenation reaction as a key step. The radical precursor, a pheno
