Synthesis of New 4-Aryl-1-(biarylmethylene)piperidines. Structural Analogs of Adoprazine (SLV313)

Hydrogena- tion of intermediate 20 in a pressure vessel in a Parr apparatus at 50 psi for 3 h afforded compound 21, which in turn was subjected to further hydrogenation at 65 psi for

In continuation of our efforts to develop new synthetic methods for impor- tant organic compounds [36, 37], we now report a novel, efficient and environmentally benign method for

A test re- action was carried out by addition of solid mesityl- magnesium bromide to a toluene solution of 1 which yielded a complex product mixture, from which only one compound

Since the reaction of amidrazones 1a – f and 4 can be described as a reaction between donor and acceptor, an increase of the donating ability would, of course, increase the yields

Firstly the formylating reagent triformamide ( 1b ) is generated from sodium diformamide ( 2 ) and methane- sulfonyl chloride in situ, which reacts with phenols 4a – f to give

In the present note we wish to report a new, even simpler method for the synthesis of aryl for- mates from phenols without isolating the formylating agent triformamide ( 1b )
