  • Thiirane - an overview | ScienceDirect Topics
    Although thiirane (3-membered) and thietane (4-membered) sulfur-containing compounds are rather rare in nature, these heterocyclic scaffolds have some biological and chemical potential, and are attractive structural motifs for drug design in medicinal chemistry and plant protection agents in agriculture
  • Thiirane - an overview | ScienceDirect Topics
    Thiirane, also known as ethylene sulfide is a three membered sulphur-containing heterocycle Generally, heterocycles containing three atoms are highly reactive due to ring strain [16] Thiirane and its derivatives have shown many pharmacological activities including anticancer, antimicrobial, and antibacterial [17]
  • Thiirane - an overview | ScienceDirect Topics
    Beer with an onion-like off-flavor was found to contain (1-methylethyl)thiirane and 2-mercapto-3-methyl-1-butanol 〈88MI 105-01〉 Thiirane is in the aroma of cooking mutton and is formed in the brewing of foods 1-Cyano-4,5-epithiopentane was the major component of rape seeds at ≥ 3 days of germination 〈85ABC217〉
  • Thiirane - an overview | ScienceDirect Topics
    Described here are methods published after 1996 for synthesis of thiirane, thiirane-1-oxide, thirane-1,1-dioxide, and thiirene-1-oxide A distinction between the approaches is based on the overall result and not on the mechanism A simple approach to the thiirane ring is the addition of a carbene or a carbenoid to a thiocarbonyl compound
  • Thiirane - an overview | ScienceDirect Topics
    Study of various modified thiirane analogs revealed that modifications on the distal phenyl ring are able to affect the binding mode of the inhibitor and tune the selectivity toward certain MMPs 48 Thus, although thiiranes 19 and 20 display similar dissociation constants for most MMPs, sulfonamide thiirane 19 behaves as a mechanism-based
  • A new and efficient method for the synthesis of thiiranes from oxirane . . .
    Various sulfur introducing reagents such as inorganic thiocyanates, 3 phosphine sulfide, 4 3-methylbenzothiazole-2-thiirane, 5 dimethylthioformamide in the presence of trifluoro acetic acid, 6 silica gel supported potassium thiocyanate, 7 indium halides KSCN 8 and polymeric cosolvent NH 4 SCN, 9 together with solvent-free conditions 10 and
  • An efficient synthesis of thiiranes from oxiranes using fluoroboric . . .
    The reactions were rapid and in most cases thiirane formation was complete in 10–20 min in excellent yields The results shown in Table 2 clearly indicate the scope and generality of this protocol as a variety of aliphatic, aromatic and allylic epoxides, including those with electron–withdrawing and electron–donating substituents
  • Thiirene - an overview | ScienceDirect Topics
    Thiirane 1-oxides and 1,1-dioxides are sometimes called episulfoxides and episulfones, and the simplest examples are often referred to as ethylene sulfoxide and ethylene sulfone The thiirane, thiirene or substitution system of nomenclature is preferred, although the episulfide terminology is often useful in general discussions of complex systems
  • Role of sulphur-heterocycles in medicinal chemistry: An update
    Thiirane, also known as ethylene sulfide is a three membered sulphur-containing heterocycle Generally, heterocycles containing three atoms are highly reactive due to ring strain [ 16 ] Thiirane and its derivatives have shown many pharmacological activities including anticancer, antimicrobial, and antibacterial [ 17 ]
