Paragraph 0182; 0192-0196, (2021/07/21)
The invention discloses a method for synthesizing a photoactive bromohydrin compound, which comprises the following steps: reacting cinnamyl alcohol as shown in a formula I, benzamide bromide as shown in a formula II, a quinine derivative, L-camphorsulfonic acid and water in a first organic solvent to obtain the bromohydrin compound as shown in a formula III. According to the method, raw materials are easy to synthesize, reaction conditions are mild, operation is easy and convenient, the yield reaches up to 47%-87%, enantioselectivity can generally reach 80% or above, and the highest point can even reach 95%.

Transformations that selectively functionalize aliphatic C-H bonds hold significant promise to streamline complex molecule synthesis. Despite the potential for site-selective C-H functionalization, few intermolecular processes of preparative value exist. Herein, we report an approach to unactivated, aliphatic C-H bromination using readily available N-bromoamide reagents and visible light. These halogenations proceed in useful chemical yields, with substrate as the limiting reagent. The site selectivities of these radical-mediated C-H functionalizations are comparable (or superior) to the most selective intermolecular C-H functionalizations known. With the broad utility of alkyl bromides as synthetic intermediates, this convenient approach will find general use in chemical synthesis.
Primary amides. A general nitrogen source for catalytic asymmetric aminohydroxylation of olefins

, p. 2221 - 2223 (2007/10/03)
(equation presented) N-Bromo,N-lithio salts of primary carboxamides have been shown to be efficient nitrogen sources for catalytic asymmetric aminohydroxylation of olefins, behaving much like the parent N-bromoacetamide in these reactions. α-Chloro-N-brom
Organic Synthesis Using Sodium Bromate. II. A Facile Synthesis of N-Bromo Imides and Amides Using Sodium Bromate and Hydrobromic Acid (or Sodium Bromide) in the Presence of Sulfuric Acid
Fujisaki, Shizuo,Hamura, Satoshi,Eguchi, Hisao,Nishida, Akiko
, p. 2426 - 2428 (2007/10/02)
The reaction of imides and amides in water (or aqueous acetic acid) with sodium bromate and hydrobromic acid (or sodium bromide) in the presence of sulfuric acid under mild conditions gave the corresponding N-bromides in high yields.
