Compound I is a densely functionalized iminohydantoin that possesses a quaternary stereocenter and is under development as an HIV protease inhibitor. Key challenges that are discussed include the preparation of a neopentyl Grignard reagent via magnesium insertion, development of a one-pot Curtius reaction that generated a volatile isocyanate and was trapped with an alc., and removal of a CBz protecting group to isolate a succinate salt. This study describes process development efforts that enabled the first scale-up of I. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Computed Properties of C4H12ClN).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Computed Properties of C4H12ClN

Photoredox B-H functionalization to selective B-N(sp³) coupling of nido-carborane with primary and secondary amines was written by Huang, Ronghui;Zhao, Weijia;Xu, Shengwen;Xu, Jingkai;Li, Chunxiao;Lu, Changsheng;Yan, Hong. And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2021.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Access to nido-carborane site-selective B-N(sp³) coupling by photoredox catalyzed B-H activation has been achieved for the first time, which leads to the synthesis of a series of nitrogen-containing nido-carboranes with moderate to good yields. This protocol is applicable to primary and secondary amines containing alkyl, or heteroaryl groups as well as sulfonamides. Furthermore, the open to air and metal-free conditions with excellent site-selectivity represent a significant improvement for B-H functionalization of nido-carboranes with organic functionalities. This study involved multiple reactions and reactants, such as Tetramethylammonium chloride (cas: 75-57-0Category: chlorides-buliding-blocks).

Tetramethylammonium chloride (cas: 75-57-0) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Category: chlorides-buliding-blocks

Benzene and pyrene can be condensed to 8,8′-positions of 3,3′-cobaltabis[1,2-carborane], while naphthalene and anthracene undergo ring contraction yielding 8,8′-indenylmethylene and 8,8′-benzo[f]indenylmethylene derivatives Benzene and pyrene can be synthetically linked to [o-COSAN]^– keeping their aromaticity. In contrast, naphthalene and anthracene are extruded in the same reaction.
