experimental part, p. 546 - 548 (2009/04/06)
A one-pot syntheses of trans-4-alkylthio- and 4-arylthio-cinnamic acids were achieved in high yields by reduction of trans-4-chlorosulfonylcinnamic acid with stannous chloride dihydrate followed by alkylation and arylation of the resulting trans-4-thiocinnamic acid with various kinds of alkyl and activated aryl halides in an aqueous medium.
Synthetic routes to ninhydrins. Preparation of ninhydrin, 5-methoxyninhydrin, and 5-(methylthio)ninhydrin
Heffner,Joullie
, p. 2231 - 2256 (2007/10/02)
Two syntheses of 5-methoxyninhydrin (2,2-dihydroxy-5-methoxy-1,3-indanedione) are described. One method employs a novel and efficient two step route, which begins with commercially available 6-methoxy-1-indanone. The application of this strategy for the preparation of a new ninhydrin derivative, 5-(methylthio)ninhydrin, and ninhydrin is also presented.
