## Abstract The glycerol carbonate synthesis from glycerol, which is an inevitable byโproduct of biodiesel production, was established. By combined sulfurโassisted carbonylation of glycerol under 1.0 MPa of carbon monoxide at 80ยฐC in DMF with oxidation by copper bromide(II), a facile synthetic meth

## Abstract 4,6โDiaminoresorcinol, which is a raw material of ZYLON (PBO fiber), has an instability in air atmosphere. Therefore, very stable benzo[1,2โd:5,4โd']bisโ2(3H)โoxazolone recognized a useful equivalent of 4,6โdiaminoresorcinol during the stages of production, storage, and transportation.
2,4-Dioxo-l,2,3,4-tetrahydroquinazoIines were easily synthesized in excellent yields by sulfur-assisted carbonylation of'2'-aminobenzamides with carbon monoxide in the presence o f a base, such as DBU or DBN.
Reductive N-heterecyclization of 2-nitrostyrenes with carbon monoxide in the presence of a catalytic amount of selenium proceeded efficiently to afford the corresponding indoles in moderate to good yields.
