摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).

摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.

权利人:LELETI RAJENDER REDDY; LIU YUGANG; PRASHAD MAHAVIR
摘要:The present invention provides a highly efficient, versatile one-step process for asymmetric synthesis of either diastereomer of 2-substituted pyrrolidines from a single starting material with excellent yields and high diastereoselectivety. Also provided is a method for the asymmetric synthesis of both diastereomers of 2-substituted piperidines with good yields and excellent diastereoselectivety. Diasteroselectivity is controlled effectively by choice of reducing agent.
