摘要:The present invention is concerned with a method of direct synthesis of co-products of at a first co-product and a second co-product. The first co-product is superhydrophilic carbon nitride thin film and the second co-product is superhydrophilic carbon nitride powder. The method has a step of using a guanidine carbonate salt as a precursor material. The present invention is also concerned with carbon nitride co-products. The carbon nitride co-products has a first co-product of superhydrophilic carbon nitride thin film and a second co-product of superhydrophilic carbon nitride powder. The superhydrophilic carbon nitride thin film has chemical formula of CN x , wherein x is 0.86-1.04, and the superhydrophilic carbon nitride powder has a chemical formula of g-C 3 N 4 .

摘要:A process for irreversible regio- and stereoselective enzyme catalyzed acylation of alcohols using enol esters as acylating reagents is disclosed. The present invention permits the selective modification of hydroxyl group(s) of chiral and meso alcohols, including sugars, organometallics, and glycosides. The enol freed upon transesterification rapidly tautomerizes to the corresponding volatile aldehyde or ketone thereby preventing the reverse reaction from occurring.

摘要:The present invention relates to a new synthesis for the preparation of 5-(substituted benzyl)-2,4-diamino-pyrimidines, including new pyrimidine derivatives. More particularly, a new synthesis of ormetoprin, diaveridine and related compounds, including novel derivatives, is disclosed. The synthesis involves the condensation of a substituted benzene and an acrylonitrile derivative to directly give enol ether intermediates, which upon subsequent reaction by known techniques with guanidine, provides the desired 5-(substituted benzyl)-2,4-diamino-pyrimidines, including novel compounds. The pyrimidine end products are useful as potentiators of sulfonamides and as antibacterial agents.
