摘要:
AbstractCyclometallated compounds, obtained by direct intramolecular C–H activation of a ligand by transition metals, are fairly reactive [especially those derived from palladium(II)] towards insertion of internal alkynes into their metal‐carbon bond. This reaction leads to either new organometallic compounds by inclusion of one to three alkynes into the M‐C bond, or organic compounds which are either carbocyclic or heterocyclic, their nature depending upon the alkyne substituents as well as upon the cyclometallated l

摘要:
AbstractThe reactions of benzene derivatives C6H5X (X = H, Cl, CH3and CF3) with hydrazine and ozone in the dark (a source of OH radicals) have been studied in a flow reactor at ambient temperature.(Substituted) phenols were formed, but these were relatively unimportant compared to N‐heterocyclic compounds (condensation products ofcis‐butenedial and analogues with hydrazine) and other (degradation) products.Benzene and (trifluoromethyl)benzene follow a similar path as toluene, also with oxidative ring opening as major reacti

摘要:
AbstractOne‐pot coupling of 2′,3′‐di‐O‐benzoyl‐uridine and 4,5,6,8‐tetra‐O‐acetyl‐3,7‐anhydro‐2‐deoxy‐D‐glycero‐D‐ido‐octitol with appropriate bifunctional phosphoro‐, phosphono‐ and thiophosphonylation reagents gave, after removal of the base‐labile protecting groups, analogues of UDP‐Glc containing charged phosphate, neutral alkyl‐ and arylphosphonate and phosphonothioate linkages. In an analogous manner, GDP‐Man analogues, in which guanosine and octitol units are similarly linked via phosphate, alkyl

摘要:
AbstractRacemic and partially protectedmyo‐inositol derivative5was coupled stereospecifically with the 2‐azido‐2‐deoxy‐glucosyl trichloroacetimidate donor8.Optical resolution of the thus obtained diastereoisomeric mixture of dimers by silica gel column chromatography, and further protective group manipulations, afforded the suitably protected title c
