Abstract:: An efficient method has been developed for the synthesis of new pyrano[3,2-c] and pyrano[3,2-a]carbazole de-rivatives via a three component reaction of 4-hydroxycarbazole or 2-hydroxycarbazole, isocyanides, and dialkylacetylenedi-carboxylates. Noteworthy features of this protocol include mild reaction conditions, catalyst-free, high atom-economy and high yields.

AbstractThe reaction of cyclic enaminones with arylidenemalono­nitriles was carried out in the presence of 13X molecular sieves in dimethyl sulfoxide. Under these mild reaction conditions, various bioactive N-aryl-4-arylhexahydroquinoline derivatives were obtained in high yields without the necessity of using transition-metal catalyst, organobase, or reflux conditions.

An iron catalyst is shown for the first time to promote transfer hydrosilylation with silyl formates and is utilized for the silylation of alcohols. Attractive features of this protocol include the use of an earth-abundant transition-metal catalyst, mild reaction conditions, and the release of gases as the only byproducts (H2 and CO2).
