Cascade reactions are green and powerful transformations for building multiple carbon-carbon bonds in one step. Through a relay olefination and radical addition process, we were able to develop the cascade Wittig/hydroalkylation reactions induced by visible light. This metal-free radical approach features mild conditions, robustness, and excellent functionality compatibility. It allows access to saturated C3 homologation products directly from aldehydes or ketones. The synthetic utility of this method is demonstrated by a two-step synthesis ofindolizidine 209D.

, (2009/04/24)
A permanent waving agent is capable of permanent waving and coloring hair simultaneously. The permanent waving agent includes: (i) a perming first agent including at least one compound represented by Formula (1) below, and an acid dye and/or an oxidation dye: wherein X is a structure selected from the group consisting of —O—, —S—, —NH— and —NR1—; R1 is an alkyl group of 1 to 6 carbon atoms; R2 is a hydrogen atom or an alkyl group of 1 to 6 carbon atoms; Y is an oxygen atom or a sulfur atom; and R is a divalent organic residue optionally having a mercapto group; and(ii) a perming second agent including an oxidizing agent.

Page/Page column 58-61, (2008/06/13)
A method of the invention industrially produces heterocyclic mercapto compounds useful as raw materials or intermediates in the synthesis of medicaments or pesticides, or as permanent wave agent, with a high yield and high productivity using easily available starting materials. A heterocyclic mercapto compound represented by Formula (1) (wherein X represents any structure of -O-, -S-, -NH-, and -NR1-; R1 represents any of an alkyl group, alkoxy group and alkoxyalkyl group each having 1 to 6 carbon atoms; Y represents an oxygen atom, a sulfur atom or -NR2-; R2represents a hydrogen atom or alkyl group having 1 to 6 carbon atoms; and Z1 represents a divalent organic residue having at least one mercapto group) is produced by reacting a metal sulfide or a metal hydrosulfide with a compound represented by Formula (2) (wherein X and Y are as defined in Formula (1); and Z2 represents a divalent organic residue having at least one halogen group) in the presence of a solvent at a pH of 7.0 to 11.0.
