A simple and green method has been developed for the synthesis of 2-aminocyclohex-l-ene-l- carboxylic esters through a one-pot three-component condensation reaction of primary amines, ethyl acetoacetate and chalcones using FeCI3/SiO2 nanoparticles in ethanol. This method has several advantages such as high to excellent product yields in short time, using an inexpensive and reusable catalyst and available starting material.

A novel and efficient route for the synthesis of 1,8-dioxooctahydroxanthenes and 14-aryl-14H-dibenzo[a,j]xanthenes is described through one-pot multi-component reaction of dimedone and 2-naphthol with various aryl aldehydes using ZnO nanoparticles under solvent-free conditions. This method provides a novel and improved pathway for the synthesis of xanthenes in the terms of excellent yields, short reaction times, reusability and low catalyst loading.

An efficient and multicomponent method has been developed for the synthesis of functionalized tricarboxamides at room temperature using CuI nanoparticles as catalyst. This method involved fivecomponent coupling reactions of Meldrum＇s acid, isocyanides with aromatic aldehydes and amines at room temperature. Atom economy, wide range of products, excellent yields in short time and mild reaction conditions are some of the important features of this protocol. Notably, this catalyst could be recycled and reused for several times without significantly decreasing the catalytic activity.

A highly efficient and general method for the synthesis of polyfunctionalized 4H-pyrans is established through a one-pot multicomponent cyclocondensation of aromatic aldehydes with CH acids, malononitrile and ethyl acetoacetate using nano silica supported tin （II） chloride as a catalyst. In this method SnCl2/nano Si02 was used as green and reusable catalyst. Excellent yields, short reaction times, simple workup, and inexpensiveness and commercially availability of the catalyst are the advantages of this method.

Indazole and its derivatives have little biological significance and have not been found in natural products due to the difficulty for living organisms to construct an N - N bond. Indazole derivatives exhibit variety of pharmacological properties such as anti-inflammatory, antidepressant, antitumor, antiarthritic and analgesic activities[1]. Different synthetic pathways generate these compounds. For instance, ring closure of pyrazole moiety, addition of hydrazine derivatives to carbonyl compounds[2] and cycloaddition reaction[3]. Herein, we report the synthesis of some new indazole derivatives by using chalcones as starting materials.

Sulfonyl hydrazide and sulfonyl semicarbazide derivatives exhibit variety of bactriostatic activity and also are important compounds as blowing agents in cellular rubber and plastics[1]. Different methods for the preparation of these compounds are reported for example, sulfonyl semicarbazides are prepared by reaction of a sulfonyl hydrazides with urea or cyanic acid[2], reaction of sulfinic acid salt with azodicarbonamide in water[3],and reaction of sulfonyl chloride and semicarbazide[4]. In lots of these methods the yields are not high, the solvents are toxic (pyridine)[5] and also the starting materials are not commericaly available[6]. We now report a modified and convenient procedure for the preparation of these compounds under solvent-free condition.
