An efficient method has been developed for the synthesis of 7′-arylspiro{adamantane-[2,3′]-(1′,2′,4′,5′,7′-tetraoxazocanes)} by the ring transformation reaction of spiro{adamantane-[2,3’]-(1′,2′,4′,5′,7′-pentaoxacane)} with arylamines in the presence of S

A general and unprecedented gold-catalyzed tandem dual heterocyclization reaction of enynones with 1,3,5-triazines has been developed, which provides bicyclic fused furans in high to excellent yields under mild reaction conditions. In addition, mechanistic studies indicate that the reaction goes through a stepwise [3+2+2]-cycloaddition of furanyl gold intermediate, which is generated from gold-catalyzed cyclization of enynone, with two molecules of formaldimines derived in situ from 1,3,5-triazine, instead of formal [4+3]-cycloaddition.

N-substituted 1,3,5-triazacyclohexanes were simply synthesized from the reaction of aromatic or fatty amines and formaldehyde catalyzed by recyclable starch sulfuric acid with good yields at room temperature.

Novel rearrangement was found by reacting anilines with HCHO/H2O2 resulting in the synthesis of various benzaldoximes. The mechanism of the rearrangement is proposed and suggested that the rearrangement might proceed via unstable N-phenyloxazirane intermediate followed by the transfer of aryl moiety from nitrogen to carbon atom leading to the formation of benzaldoxime.
Conformational Study of 1,3,5-Tris(o-methoxyphenyl)-1,3,5-triazacyclohexane and 1,3,5-Tris(p-methoxyphenyl)-1,3,5-triazacyclohexane

The triazacyclohexane ring in both title compounds, C24H27N3O3 (1a) and C24H27N3O3 (1b), adopts a chair conformation with an equatorial-diaxial orientation of the aryl groups.The repulsion between axial groups is relieved by the displacement of the N-C(ar
