Palladium-catalyzed Substitution Reaction of Allylic Derivatives with Tinacetylene.
The substitution reaction of allylic derivatives (acetate, carbonate, and chloride) with tinacetylene proceeded in the presence of palladium as a catalyst to give a product having a 1-ene-4-yne system.
متن کاملNovel Resorcinol Derivatives from Lasiodiplodia theobromae
Two novel resorcinol derivatives were isolated from the mycelium of Lasiodiplodia theo bromae IFO 31059 as potato micro-tuber inducing compounds. Their structures were estab lished by spectroscopic methods as ethyl (6 ' 7?)-2,4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (8) and isobutyl (6 ' /?)-2.4-dihydroxy-6-(6'-hydroxyheptyl)benzoate (9). The absolute stereo chemistry of the asymmetric cente...
متن کاملAntidermatophytic Action of Resorcinol Derivatives: Ultrastructural Evidence of the Activity of Phenylethyl Resorcinol against Microsporum gypseum.
In this work, we evaluated the antidermatophytic activities of three resorcinol derivatives that have a history of use in dermo-cosmetic applications to discover molecules with multiple dermatological activities (i.e., multi-target drugs), thereby reducing the cost and time necessary for new drug development. The antidermatophytic activities of the three skin lighteners were evaluated relative ...
متن کامل[Fluorophothometric determination of aldehyde by utilizing condensation reaction with resorcinol].
A simple and sensitive fluorophotometric method for the determination of aldehyde was established by utilizing condensation reaction with resorcinol. In the determination of vanillin that is one of aldehydes, the calibration curve exhibited linearity over the vanillin concentration range of 3.0-7600 ng ml(-1) at an emission wavelength of 507 nm with an excitation of 410 nm and with the relative...
متن کاملViii. a Specific Colour Reaction for Ergosterol
THE unique function of ergosterol as the parent substance of vitamin D made it desirable to find a colour reaction for it, by means of which it could be detected in the presence of other sterols. In searching for such a reaction, the property of formaldehyde of shifting the colour from the red into the blue part of the spectrum in the usual colour reactions of sterols [Whitby, 1923; Rosenheim, ...
