The present invention relates to the design and synthesis of a class of novel chiral phosphine ligand, 1,2-bis(diphenylphosphinoalkylamido)-1,2-disubstituted ethane, and use in asymmetric catalytic reactions, such as asymmetric catalytic synthesis of pyrazoline-5-one with a chiral quaternary carbon center, i.e., highly enantioselective synthesis of 3-methyl-4-benzyl-4-(2-butyl-2,3-butadienyl)pyrazoline-5-one by using 3-methyl-4-benzylpyrazoline-5-one and benzyl (2-butyl-2,3-butadienyl) carbonate with tris(dibenzylideneacetone)dipalladium-chloroform adduct and this novel ligand as catalysts. The ligand designed by this present invention has the following advantages: the structure is novel, the synthesis and enlarge are simple, the enantioselective control effect in the practical reaction is excellent, which has a broad application prospect in chiral catalysis.

Various embodiments of an apparatus, method(s), system(s) and computer program product(s) described herein are directed to a Reminder Engine. The Reminder Engine detects a selection, by a first user account, of one or more reminder attributes for a message received in an online chat session. The Reminder Engine generates a reminder object for the message according to the one or more selected reminder attributes. The Reminder Engine receives a reminder notification based on expiration of a duration attribute associated with the reminder object.

Methods, systems, and apparatus, including computer programs encoded on computer storage media related to a method for dynamic sharing of meeting assets within a messaging platform. A communication system receives one or more meeting assets that are associated with a meeting that was conducted via a video communication platform. After the meeting has ended, the communication system generates a meeting summary component configured to be displayed within the messaging platform. The meeting summary component may include information describing the meeting and meeting assets. The meeting summary component may be posted into a messaging channel of the messaging platform.
