The use of two silicon carbide plates is reported for the preparation of three libraries of organic molecules using microwave heating. In addition, a preliminary study has been carried out, showing that one of the plates can also be used in a proteomics setting. Both the 24-position and 48-position plates heated evenly when irradiated with microwave energy. The 48-position plate was used to prepare a library of N-aryl functionalized β-amino esters via an aza-Michael reaction between anilines and Michael acceptors. The 24-position plate was used to prepare a library of biaryls via a Suzuki coupling methodology and a library of 1,4-dihydropyridines via a Hantzsch synthesis. The 48-position plate was also used to perform the proteolytic digestion of insulin chain B by trypsin.

An unexpected and greensynthesis of azapodophyllotoxin derivatives was realized via microwave-assistedmulticomponentreactions of dimedone, tetronic acid, and aromatic aldehydes in ammonia water. This protocol has the advantages of environmental friendliness, short reaction time, good yields, low cost, and easy operation.

Microwave (MW) assisted synthesis of acridine and quinazolinederivatives was performed on thin layer chromatography (TLC) plates. This versatile, simple and economical green methodology is readily amenable to parallel synthesis of acridine and quinazoline compound libraries.
Evaluation of sodium acetate trihydrate–urea DES as a benign reaction media for the Biginelli reaction. Unexpected synthesis of methylenebis(3-hydroxy-5,5-dimethylcyclohex-2-enones), hexahydroxanthene-1,8-diones and hexahydroacridine-1,8-diones
