Paragraph 0173; 0175-0176, (2021/08/06)
The present invention provides an amidite compound represented by formula (1) which enables a synthesis of RNA with high purity, and the method for preparing a polynucleotide by using the same compound. (In the formula (1), wherein R represents the following formula (wherein Ra and Rb are identical to or different from each other and each represents a methyl group, an ethyl group, or a hydrogen atom, with the proviso that Ra and Rb does not represent a hydrogen atom, n is an integer of 1 to 5), and Ba represents a group containing optionally protected nucleobase structure, and G1 and G2 are identical to or different from each other and each represents a protecting group for a hydroxy group, and G3 are identical to or different from each other and each represents an alkyl group.

Functionalized pyrazoles are generated from secondary propragyl alcohols and hydrazines in a ruthenium-catalyzed cascade process, consisting of redox isomerization, Michael addition, cyclocondensation and dehydrogenation steps. The same bifunctional catalyst mediates the conversion of tertiary propargyl alcohols with hydrazine to 3-hydroxynitriles via anti-Markovnikov hydroamination followed by elimination of ammonia.

The hydrido silyl iron complex (o-Ph2PC6H4SiMe2)Fe(PMe3)3H (2) was obtained via the activation of the Si-H bond of the bidentate silyl ligand o-Ph2P(C6H4)SiMe2H (1) by Fe(PMe3)4. 2 showed good to excellent catalytic activity in both the reduction of aldehydes/ketones and the dehydration of benzamide. In addition, with complex 2 as a catalyst, α,β-unsaturated carbonyls could be selectively reduced to the corresponding α,β-unsaturated alcohols. The mechanisms of the formation of 2 and the catalytic dehydration process are proposed and partly experimentally verified.
