An efficient and novel route for assembling pyrrolo/piperido[1,2-a]indoles is portrayed involving a radical-mediated reductive epoxide opening reaction of N-tethered epoxy-indoles that trigger facile intramolecular cyclization followed by an oxidative quenching step. Capitalizing on the operational simplicity of the method involving just two steps and use of an efficient C-C bond-forming reaction, this radical-based protocol enables the modular assembly of an important class of N-fused indole derivatives with versatile functional and structural diversity.

Paragraph 0027; 0028; 0029, (2017/05/02)
The present invention discloses a 4-mercapto-1-butanol synthesis process, which comprises: 1) dissolving 1,4-butanediol and an acid-binding agent in an organic solvent I, adding a sulfonylation agent in a dropwise manner to carry out a sulfonylation reaction, carrying out extraction separation with dichloromethane, and carrying out washing, drying and concentration to obtain a colorless oil-like substance; and 2) dissolving the colorless oil-like substance obtained in the step 1) in an organic solvent II, adding a nucleophile to carry out a nucleophilic substitution reaction, and finally carrying out pressure reducing distillation to obtain the 4-mercapto-1-butanol. According to the present invention, the completely-new 4-mercapto-1-butanol synthesis route is provided, the used raw materials are easy to obtain, the operation is simple, the reaction conditions are not harsh, and good industrial values are provided.

experimental part, p. 6002 - 6009 (2009/12/26)
(Chemical Equation Presented) A convergent and high-yielding approach for the asymmetric synthesis of sulforaphane 2 and four analogues differently substituted at the sulfinyl sulfur has been developed. The key step of the synthesis is the diastereoselect
