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).

权利人:UNIV CITY HONG KONG
摘要:The present invention is concerned with a method of direct synthesis of co-products of at a first co-product and a second co-product. The first co-product is superhydrophilic carbon nitride thin film and the second co-product is superhydrophilic carbon nitride powder. The method has a step of using a guanidine carbonate salt as a precursor material. The present invention is also concerned with carbon nitride co-products. The carbon nitride co-products has a first co-product of superhydrophilic carbon nitride thin film and a second co-product of superhydrophilic carbon nitride powder. The superhydrophilic carbon nitride thin film has chemical formula of CN x , wherein x is 0.86-1.04, and the superhydrophilic carbon nitride powder has a chemical formula of g-C 3 N 4 .
