Regio- and stereoselective reactions of (S)-(1-methylpyrrolidin-2-yl)methyl allyl sulfide

Archives of Pharmacal Research, 1991
The synthesis and regioselective reactions of a chiral allyl sulfide, (S)-(+)-(1-methylpyrrolidin-2-yl)methyl allyl sulfide (MAS.1) are described. Remarkable α-regioselectivity was observed in the alkylation of the carbanion of MAS while 1∶3 mixtures of α-and γ-adducts were produced in the addition of the MAS anion to aldehydes.

GAS-PHASE THERMOLYSIS OF SULFUR COMPOUNDS. PART V. METHYL ALLYL, DIALLYL AND BENZYL ALLYL SULFIDES

Phosphorus and Sulfur and the Related Elements, 1982
Abstract The title compounds have been pyrolyzed in a stirred-flow system, at temperatures within the range 315–418°C and pressures between 2 and 15 torr. Under these conditions, the products observed were propene and the polymers of thiomethanal, allyl thioaldehyde and benzyl thioaldehyde.

The Thio-Wittig Rearrangement of Deprotonated Allyl Methyl Sulfide. A Gas-Phase Unimolecular Isomerization Probed with a Variable Temperature Flowing Afterglow-Triple Quadrupole Device

Journal of the American Chemical Society, 1996
The thio-Wittig rearrangement of deprotonated allyl methyl sulfide has been examined in the gas phase with a variable temperature flowing afterglow-triple quadrupole device. Collision-induced dissociation studies of a series of thiolate anions (RS-) reveal that methyl deprotonation leads to 3-butene-1-thiolate (2a), the [2,3]-Wittig product, while 1 ...

Inhibition by Allyl Sulfides and Phenethyl Isothiocyanate of Methyl-n-pentylnitrosamine Depentylation by Rat Esophageal Microsomes, Human and Rat CYP2E1, and Rat CYP2A3

Nutrition and Cancer, 2004
Garlic and Cruciferae are associated with reduced risks of several human cancers, and some of their constituents are anticarcinogenic in animals. Here we studied inhibition of in vitro metabolism of the rat esophageal carcinogen methyl-n-pentylnitrosamine (MPN) by garlic-derived allyl sulfides and by Cruciferae-derived phenethyl isothiocyanate (PEITC ...

Effect of paclitaxel along with di allyl sulfide on immuno competent cells, immune complexes and immunoglobulins changes in 7,12 Di Methyl Benz(A) anthracene induced skin cancer in Wistar rats.

International Journal of Medical Research & Health Sciences, 2014
Our recent studies have shown that naturally occurring dietary organo sulfure compounds such as di allyl sulfide and paclitaxel are capable of inhibiting polycyclic aromatic hydrocarbon (PAH) metabolism and subsequent PAH-DNA adduct formation in Wistar rats. In this study these plant phenols were tested for their effects against PAHs and 7,12 Di Methyl

Exploring the distinct conformational preferences of allyl ethyl ether and allyl ethyl sulfide using rotational spectroscopy and computational chemistry.

Journal of Chemical Physics, 2023
The conformational energy landscapes of allyl ethyl ether (AEE) and allyl ethyl sulfide (AES) were investigated using Fourier transform microwave spectroscopy in the frequency range of 5-23 GHz aided by density functional theory B3LYP-D3(BJ)/aug-cc-pVTZ ...

Reactivity of allyl methyl sulphide, the in-vitro metabolite of garlic, with some amino acids and with phospholipid involved in viral infections

Journal of Biomolecular Structure and Dynamics, 2020
Garlic, as well as several natural food ingredients such as basil, ginger, turmeric, cinnamon, clove, pepper etc., has long been traditionally used as routine anti-viral and anti-bacterial remedy.
