Abstract
A solid phase synthetic method is disclosed in which the usual solid phase synthetic steps are carried out and the spent solid phase support is reacted to form a volatilizable compound upon cleavage of the reaction product from the solid phase support. The cleaved product is then separated from the volatile compound by volatilization of that compound. Exemplary solid supports that form a volatilizable compound are also disclosed.
Claims19
In a solid phase synthesis method wherein at least one reagent is coupled to a solid phase support, a plurality of reactions are carried out upon the solid phase-coupled reagent to form a solid phase-coupled reaction product and that reaction product is cleaved from the solid phase support to form a cleaved product, the improvement in which the solid phase support is converted to a volatile compound that is separated from the cleaved product by vaporization of that the volatile compound, leaving behind said cleaved product, and said cleaved product is recovered.
In a solid phase synthesis method wherein at least one reagent is coupled to a solid phase silica-based support, a plurality of reactions are carried out upon the solid phase-coupled reagent to form a solid phase-coupled reaction product and that reaction product is cleaved from the solid phase support to form a cleaved product, the improvement in which the silica-based solid phase support is reacted with HF to convert said silica-based solid phase support into a volatile compound that is separated from the cleaved product by vaporization of the volatile compound, leaving behind said cleaved product, and said cleaved product is recovered.
