Simple exploration of 452339-73-0

Any one of these steps may be slow and thus may serve as the rate determining step. In general, however, in the presence of the catalyst, the overall rate of the reaction is faster than it would be if the reactants were in the gas or liquid phase.

452339-73-0, The molecularity of an elementary reaction is the number of molecules that collide during that step in the mechanism. If there is only a single reactant molecule in an elementary reaction, that step is designated as unimolecular. 452339-73-0, name is (R)-5-(2,2-Dimethyl-4H-benzo[d][1,3]dioxin-6-yl)oxazolidin-2-one. A new synthetic method of this compound is introduced below.

A solution of (5R)-5-(2, 2-dimethyl-4H-1, 3-benzodioxin-6-yl)-1, 3-oxazolidin-2-one (Example 1 viii) (503mg) in DMF (10mL) was treated with sodium hydride (60% dispersion in mineral oil) (97mg) under nitrogen for 20 min. A solution of 1-[2-(benzyloxy) ethoxy] -4- (2-bromoethyl) benzene (676mg) in DMF (5 mL) was added and the reaction stirred for a further 2 h. The reaction mixture was concentrated in vacuo then the residue was prified by chromatography (Biotage, 40g) eluting with EtOAc-petroleum ether (2: 3) to give the title compound (585mg). LCMS RT = 3.66 min
