Reaction Steps

2-Furoyl chloride (6.5 gm, 0.05 m) was dissolved in methylene chloride- (200 ml), cooled to 0° to -5° C. and maintained under a nitrogen atmosphere. Triethylamine (10 ml) and then dimethylpropargylamine (4.2 gm, 0.051 m) were gradually added with stirring while maintaining the temperature at 0°±5° C. for about one-half hour and then at room temperature for about 1 hour. Water .(100 ml) was added and the reaction slurry was transferred, using methylene chloride (100 ml ) as a rinse, to a separatory funnel. The aqueous layer was sequentially separated and the methylene chloride layer was washed with water (50 ml ), 5% hydrochloric acid (1×100 ml ), saturated sodium bicarbonate (1×50 ml), water (1×50 ml) and then brine. The solvent was evaporated after drying over magnesium sulfate and 8.0 gms of product were obtained. The starting materials for all compounds except 7, 8 and 11 can be prepared in an analogous manner.
