Ammonium chloride catalyzed microwave-assisted synthesis of tetrahydrobenzo[b]pyrans
In the present work, we have developed a mild, efficient, and environmentally benign method for the synthesis of tetrahydrobenzo[b]pyran derivatives via a three-component cyclocondensation of aldehydes, malononitrile and dimedone utilizing ammonium chloride as a simple, easily available and cost effective catalyst under microwave irradiation. This method has several attracting features such as ...

متن کاملReduction of Aldehydes and Ketones with LiBH4 Under Microwave Irradiation
A variety of aldehydes and ketones have been reduced to their corresponding alcohols within 30-240 secondswith excellent yields (92-97%) of products by LiBH4 under microwave irradiation in H2O as green solvent.
متن کاملChemoselective Oxidation of Benzyl, Amino, and Propargyl Alcohols to Aldehydes and Ketones under Mild Reaction Conditions
Catalytic oxidation reactions often suffer from drawbacks such as low yields and poor selectivity. Particularly, selective oxidation of alcohols becomes more difficult when a compound contains more than one oxidizable functional group. In order to deliver a methodology that addresses these issues, herein we report an efficient, aerobic, chemoselective and simplified approach to oxidize a broad ...
متن کاملCopper-catalyzed three-component cascade reaction of alkynes, sulfonyl azides and simple aldehydes/ketones.
A copper-catalyzed dimethylzinc-promoted three-component cascade reaction of alkynes, sulfonyl azides, and simple aldehydes or ketones is described. Polysubstituted olefins were thus constructed expeditiously in a one-pot procedure under mild conditions.
