Understanding All The Noncovalent Forces Involved Has The Potential To Allow De Novo Catalysis Design,And As A Step Toward This,Understanding How To Control The Charge State Of Ionizable Groups Represents A Powerful Yet Straightforward Approach To Probing Complex Systems. Here We Utilize Supramolecular Capsules Assembled Via The Hydrophobic Effect To Encapsulate Guests And Control Their Acidity. We Find That The Greatest Influence On The Acidity Of Bound Guests Is The Location Of The Acidic Group Within The Yoctoliter Space. However,The Nature Of The Electrostatic Field Generated By The (Remote) Charged Solubilizing Groups Also Plays A Significant Role In Acidity,As Does Counterion Complexation To The Outer Surfaces Of The Capsules. Taken Together,These Results Suggest New Ways By Which To Affect Reactions In Confined Spaces. Doi:10.1021/jacs.0C00907

The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.
