چکیده

2,4,6-triisopropylstryrene was synthesized in a single step via the witting reaction from the corresponding aldehyde. the reaction of three styrene's derivatives, 2,6-dimethylstyrene, 2,4,6-trimethylstyrene, and 2,4,6- triisopropylstyrene with 4-methyl-l,2,4-triazoline-3,5-dion(m etd) was investigated. these reactions are instantaneous at room temperature and lead to the formation of 2: 1 adducts in high yield via double diels-alder reactions. in each case the initially formed 1:l diels-alder adduct is extremely reactive, and was not isolated. it readily undergoes the second diels- alder reaction with metd. these 2:l adducts wete fully characterized by ir, cnmr(o ff- resonace, inept, multiplicity determination sequence techniques), mass spectra, 'hnmr and elemental analysis.

Synthesis and potential antimycotic activity of 4-substituted-3-(thiophene-2-yl-methyl)-Delta2-1,2,4-triazoline-5-thiones.

In the reaction of hydrazide of thiophene-2-acetic acid (1) with isothiocyanates, the respective thiosemicarbazides 2a-g were obtained. Further cyclization with 2% NaOH led to formation of 4-substituted-3-(thiophene- 2-yl-methyl)-Delta2-1,2,4-triazoline-5-thiones (3a-g). These compounds showed promising antimycotic activity.

4-Hydrazinyl­idene-1-methyl-3H-2λ6,1-benzothia­zine-2,2-dione

In the title compound, C(9)H(11)N(3)O(2)S, the thia-zine ring adopts a half-chair conformation. In the crystal structure N-H⋯N hydrogen bonds connect two mol-ecules into a centrosymmetric dimer, forming an R(2) (2)(6) ring motif. These dimers are further connected into chains by N-H⋯O and C-H⋯O hydrogen bonds.

Microbial Formation of Substituted Styrenes

Various monoand disubstituted cinnamic acid derivatives and aromatic carboxylic acids with saturated side chains were incubated mainly with Bacillus, Candida, Hansenula, and Saccharo­ m yces strains. The cinnamic acids carrying a hydroxyand/or a methoxy group at the 3and/or 4-position of the benzene ring were decarboxylated with high yields. Most of the reactions were terminated within 24 to 48...
