标题:Influence Of Superfluidity On Recombination Reactions Of H + T-> Ht And T + T-> T2 In 3He−4He Quantum Media Under Saturated Vapor Pressure At 1.6 K
摘要:An Influence Of Superfluidity On Chemical Reaction Has Been Studied In The Recombination Reactions Of Hydrogen (H) And Tritium (T) Atoms,H + T--> Ht And T + T--> T-2,In He-3-He-4 Mixture Solutions At 1.6 K. The Reactive Species,H And T Atoms,Were Produced In The Mixture Through The Nuclear Reaction,He-3 + N--> P(H) + T. Experimental Yield Ratio Of Ht To T-2 Was 110 +/-17 In Normal-Fluid Solution. However,In Superfluid Solution,The Value Decreased To 60 With A Decrease In Atomic Fraction Of He-3. A Two-Fluid Model Was Applied To Estimate The Contribution Of Superfluidity. The Calculated Yield Of Ht To T-2 In The Superfluid Component Became Almost A Constant Value Of 56 +/-14 Over The Whole Range Of Superfluid Solution Studied. On The Basis Of Preferential Formation Of Ht Over T-2 And A Computer Simulation Of Relative Rate Constants,Formation Of Hydrogen Isotope Bubbles And Their Tunneling Recombination Were Proposed.

摘要:Embodiments of the present application relate to the preparation of 2′-O-protected nucleoside phosphoramidites and conjugation of the 2′-O-protected nucleoside to a solid support. More specifically, the present application relates to nucleosides having a hydroxy protecting group at the 2′ position that reduces migration to the 3′ position during RNA (e.g., mRNA) synthesis and can be readily removed under mild conditions without the use of toxic metal-containing reagents. Methods of using the nucleosides described herein in RNA synthesis are also disclosed.

标题:Photoactivatable two-stage protective groups for the synthesis of biopolymers
发明人：GUEIMIL RAMON; SCHEFFLER MATTHIAS; BEIJER BARBRO
权利人:FEBIT HOLDING GMBH
摘要:The present invention relates to a process for synthesizing biopolymers by stepwise assembly from protected synthesis building blocks which carry two-stage protective groups. The two-stage protective groups are activated by a first illumination step and eliminated by a subsequent chemical treatment step. Photoactivatable components which considerably speed up the activation process via intramolecular triplet sensitizers or/and have fluorescence properties are used. The two-stage protective groups can be used in particular within the framework of quality control.
