Free-ZnO nanoparticles have been employed as a mild, efficient and reusablecatalyst for the one-pot multicomponent synthesis of tetrahydrobenzo[b]pyrans and dihydropyrimidones in excellent yields. The ZnO NPs were recycled and reused eight times.
游离ZnO纳米颗粒已被用作温和,有效和可重复使用的催化剂,以优异的收率一锅多组分合成四氢苯并[ b ]吡喃和二氢嘧啶。ZnO NP被回收再利用八次。

This invention provides methods for attaching a nucleic acid to a solid surface and for sequencing nucleic acid by detecting the identity of each nucleotide analogue after the nucleotide analogue is incorporated into a growing strand of DNA in a polymerase reaction. The invention also provides nucleotide analogues which comprise unique labels attached to the nucleotide analogue through a cleavable linker, and a cleavable chemical group to cap the —OH group at the 3′-position of the deoxyribose.
