Condensationtion of 3-hydroxy pyridine alkyl isocyanides and dialkyl acetylenedicarboxylate: synthesis of 4H-chromenes
The reactive intermediate generated by the addition of tert-butyl and 1,1,3,3-tetramethyl butyl isocyanide and cyclohexyl isocyanide to dialkyl acetylenedicarboxylate was trapped by 3-hydroxy pyridine to produce highly functionalized 4H-chromenes in fairly good yields.

متن کاملA New synthesis of functionalized imidazo[2,1-b][1,3]thiazines with thiohydantoins, isocyanides and dialkyl acetylenedicarboxylates
The reaction of stoichiometric amounts of dialkyl acetylenedicarboxylates with alkyl isocyanides and 5,5-diaryl thiohydantoins in toluene and catalytic amount of p-TSA afforded imidazo[2,1-b][1,3]thiazines in good overall yields
متن کاملSeparation of ( 3 . 14 C ) 3 - Hydroxy . 3 - methylglutaric acid from ( 3 _ 14 C ) 3 - Hydroxy - 3 - methylglutaryl CoA using Sephadex G - 15 column chromatography
A new method has been developed for the separation of (314C) 3-Hydroxy-3-methylglutaric acid from a (3_ 14C) 3-Hydroxy-3-methylglutaryl CoA preparation using Sephadex G-15 column chromatography. This method is simple, rapid and is useful in studies whe1'e the preparation of (3_ 14C) 3-Hyd1'oxy-3-methylglutaryl CoA is requi1'ed to bef1'eef1'Om (3_ 14C) 3-Hyd1'oxy-3-methylgluta1'ic acid contamina...
