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 for the synthesis of polycyclic aromatic hydrocarbons and synthesis platforms for performing such syntheses are provided. Methods and platforms are provided that allow for the synthesis of aza-polycyclic aromatic hydrocarbons by an expedient ring assembly. Methods and platforms allow for a modular approach to synthesis that provide multiple new C—C bonds in sequential pericyclic reactions, thus giving access to compounds with multiple axes of substitution.

摘要:The disclosure provides a method for synthesizing free base forms of (2R,6R)-hydroxynorketamine (HNK) and (2S,6S)-hydroxynorketamine. In an embodiment synthesis of (2R,6R)-hydroxynorketamine (HNK) includes preparation of (R)-norketamine via chiral resolution from racemic norketamine via a chiral resolution with L-pyroglutamic acid. The disclosure also provided crystal forms of the corresponding (2R,6R)-hydroxynorketamine (HNK) and (2S,6S)-hydroxynorketamine hydrochloride salts.

标 题 :Processes for the synthesis of pentafluorobutane and the separation of hydrogen fluoride and pentafluorobutane mixtures
发明人：REIF FERDINAND; BALTHASART DOMINIQUE
权利人:SOLVAY
摘要:The invention relates to a process of separation of mixtures containing HFC-365mfc/HF azeotropic compositions by two distillations at different pressures, as well as to a process of synthesis of HFC-365mfc which integrates this process of separation and a recycling of certain fractions towards the hydrofluorination step.
