alternative synthesis
2.Chemical synthesis based on C1 chemistry is the most important alternative to the synthesis based on petroleum.
3.Abstract: A novel enzymatic reaction—ammonolysis was introduced in thenineties.This reaction not only provides a synthetically useful and mild alternative method for the synthesis of amides,but also can be used for the kinetic resolution of chiral alcohols or chiral carboxylic acids.In addition to enantioselective hydrolysis,esterification and transesterification,ammonolysis also shows high enantioselectivity in the resolution of racemates.
4.Several alternative non-phosgene methods for DPC synthesis have also been proposed. Among them, the transesterification of dimethyl oxalate (DMO) with phenol to diphenyl oxalate (DPO) followed by decarbonylation of DPO to DPC is a promising process.
5.Those awards and winners of the US Presidential Green Chemistry Challenge Awards in 2004 were introduced including: ① Alternative Synthetic Pathways Award: Development of a green synthesis for Taxol manufacture via plant cell fermentation and extraction, Bristol-Myers Squibb Company;
6.a redesigned efficient synthesis of Aprepitant(alternative synthetic pathways award),a UV-curable,one-component,low-VOC refinish primer(alternative solvents and reaction conditions award),a nonvolatile reactive coalescent Archer RC?
