摘要:
An instrument and process for accelerating the solid phase synthesis of peptides is disclosed. The method includes the steps of deprotecting a protected first amino acid (10) linked to a solid phase resin (14) by admixing the protected linked acid (10) with a deprotecting solution in a microwave transparent vessel while irradiating the admixed acid and solution with microwaves, then activating a second amino acid (20) by adding the second acid (20) and an activating solution (22) to the same vessel while irradiating the vessel with microwaves, then coupling the second amino acid (20) to the first acid (10) while irradiating the composition in the same vessel with microwaves, and cleaving the linked peptide from the solid phase resin (14) by admixing the linked peptide with a cleaving composition in the same vessel while irradiating the composition with microwaves.

A controlled-flow microwave instrument is disclosed for chemical synthesis using heterogeneous or highly viscous starting materials. The instrument includes a microwave source (10) for generating electromagnetic radiation in the microwave frequencies, a microwave cavity (11) in wave communication with the source for exposing compositions placed therein to microwave radiation, a microwave-transparent pressure resistant reaction vessel (13) in the cavity, a source reservoir (15) for starting materials and related compositions, a pump (17) in communication with the source reservoir for pumping heterogeneous or highly viscous materials from the source reservoir to the reaction vessel, and a pressure-resistant valve (34) between the pump and the reaction vessel for isolating the reaction vessel from the pump and the source reservoir during application of microwave energy to compositions in the vessel and from any resulting high pressures generated therein.
