Some 2-amino-4,6-diarylpyrimidines 2 have been prepared from substituted benzylideneacetophenones and guanidine hydrochloride in presence of alkali by conventional heating in alcoholic medium and microwave heating in solvent-free conditions. N-(2,3,4,6-Tetra-O-acetyl-β-D-glucopyranosyl)-N'-(4',6'-diarylpyrimidine-2'-yl)thioureas 4 have been synthesized by reaction of per-O-acetylated glucopyranosyl isothiocyanate 1 and substituted 2-amino-4,6-diarylpyrimidines 2. Two different methods have been used, namely refluxing in anhydrous dioxane and solvent-free microwave-assisted coupling. The second procedure afforded higher yields in much shorter reaction times. The compounds 2 and 4 were tested for their antibacterial and antifungal activities in vitro against Staphylococcus epidermidis, Enterobacter aerogenes and Candida albicans by disc diffusion method.

A new fast and direct synthesis for tripodal fatty acid esters of tris-hydroxyethyl isocyanurate 1 under microwave irradiation is developed. The method is valid for saturated and unsaturated acids, but the last produced a mixture of esters cis and trans.

Some compounds of N-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-N'-(benzothiazole-2'- yl)thioureas have been synthesized from corresponding 2,3,4,6-tetra-O-acetyl-β-Dglucopyranosyl isothiocyanate and the substituted derivatives of 2-aminobenzothiazoles executing in home microwave oven. Their spectroscopic properties have been recorded and the relationships between their structures and spectral properties (IR, 1H- and 13C-NMR) have been discussed.

N‐(2,3,4,6‐tetra‐O‐acetyl‐β‐D‐glucopyranosyl)‐N'‐(thiazol‐2'‐yl)thioureas have been synthesized from corresponding 2,3,4,6‐tetra‐O‐acetyl‐β‐D‐glucopyranosyl isothiocyanate and the substituted derivatives of 2‐aminothiazoles executing in domestic microwave oven. The 1H and 13CNMR spectra of some derivatives of N‐(2,3,4,6‐tetra‐O‐acetyl‐β‐D‐glucopyranosyl)‐N'‐(4'‐arylthiazole‐2'‐ yl)thiourea have been recorded. The magnetic signals in their NMR spectra show the relationships between the structure and positions of the substituted groups. It's also indicated that the substitution in the thiazole ring influenced on the chemical shift of proton on thiourea group. 2‐Iminothiazolidin‐4‐ones have been synthesized from ethyl bromoacetate and substituted N‐(2,3,4,6‐tetra‐O‐acetyl‐β‐Dglucopyranosyl)‐ N'‐(phenylthiazole‐2'‐yl)thioureas. The presence of 2‐iminothiazolidin‐4‐one isomers were confirmed by NMR spectroscopies.

A summary of detailed studies of influence of microwave irradiation on the kinetics of Knoevenagel condensation was presented. General conclusions were outlined.

A fast and efficient method has been developed for the synthesis of Thiocarbamic acid [(thiophene-2-yl) ethylidene]hydrazide, [TTEH], under microwave irradiation. This compound has been characterized by FT-IR, ¹H-NMR, ¹³C-NMR.

We report the cross-coupling of n-hexanol and aryl iodides using Cu(I) catalysis under microwave reaction conditions. The aryl ethers were obtained in good yield. The use of 1,10-phenanthroline as the ligand was found effective in these reactions.

Enzymatic hydrolysis of potato starch by γ-amylase was investigated to reveal the potential coupling mechanism of MIECC. The MIECC effect on increasing initial reaction rate ~2.5 times was observed in case of low viscous reaction system i.e. low substrate concentration. Up to now amylases were known as microwave sensitive enzymes, that are strongly deactivated when placed in microwave filed. Conducted experiments testifies on γ-amylase specific activation done by microwaves.

Microwave irradiation of N-[2-(phenylmethyl)phenyl]benzamide with potassium tert-butoxide leads to a 1:1 ratio of the expected product from Madelung's reaction and 9H-Dibenzo[a,c]carbazole. This one seems to come from a competitive reaction pathway rather than from thermal conrotatory electrocyclic of 2,3-diphenyl- 3H-Indole.

Three steps synthesis of neoflavonoid skeleton (4 hydroxybenzophenone imine was carried out in good yield. The key step is a microwave assisted solventless Knoevenagel condens decarboxylation is involved.
