1,3,5-Trithiane is the chemical compound with the formula (CH2S)3. This heterocycle is the cyclic trimer of the otherwise unstable species thioformaldehyde. It consists of a six-membered ring with alternating methylene bridges and thioether groups. It is prepared by treatment of formaldehyde with hydrogen sulfide.Trithiane is a building block molecule in organic synthesis, being a masked source of formaldehyde. In one application, it is deprotonated with organolithium reagents to give the lithium derivative, which can be alkylated.(CH2S)3 + RLi → (CH2S)2(CHLiS) + RH(CH2S)2(CHLiS) + R’Br → (CH2S)2(CHR’S) + LiBr(CH2S)2(CHR’S) + H2O → R’CHO + ….Trithiane is the dithioacetal of formaldehyde. Other dithioacetals undergo similar reactions to the above.It is also a precursor to other organosulfur reagents. For example, chlorination in the presence of water affords the chloromethyl sulfonyl chloride:(CH2S)3 + 9 Cl2 + 6 H2O → 3 ClCH2SO2Cl + 12 HCl^ David R. Lide, ed.

It has a clear to light yellow sludgy appearance. It will detonate under strong shock. High temperatures, whether by sudden heating of any quantity, or by the accumulation of heat when large quantities are burning, will also cause detonation. The material can react vigorously with reducing materials and is incompatible with sodium dichromate or sulfuric acid. It must be stored in a cool, ventilated place, away from acute fire hazards and easily oxidized materials. It also reacts violently with aluminium, boron phosphide, cyanides, esters, PN2H, phosphorus, NaCN, SnC12, sodium hypophosphite, thiocyanates, etc. When heated to decomposition it emits highly toxic fumes of NOx. It is an extremely powerful oxidizing agent which may cause violent reaction with reducing materials.

1,3-Beta-glucan synthase is a glucosyltransferase enzyme involved in the generation of beta-glucan in fungi. It serves as a pharmacological target for antifungal drugs such as caspofungin, anidulafungin, and micafungin.The biosynthesis of disaccharides, oligosaccharides, and polysaccharides involves the action of hundreds of different glycosyltransferases. These enzymes catalyse the transfer of sugar moieties from activated donor molecules to specific acceptor molecules, forming glycosidic bonds. A classification of glycosyltransferases using nucleotide diphospho-sugar, nucleotide monophospho-sugar and sugar phosphates (EC 2.4.1.-.), and related proteins into distinct sequence-based families has been described. This classification is available on the CAZy (CArbohydrate-Active EnZymes) web site . The same three-dimensional fold is expected to occur within each of the families. Because 3-D structures are better conserved than sequences, several of the families defined on the basis of sequence similarities may have similar 3-D structures and, therefore, form 'clans'.This is the glycosyltransferase 48 family, which consists of various 1,3-beta-glucan synthase components including Gls1, Gls2, and Gls3 from yeast. 1,3-Beta-glucan synthase (EC 2.4.1.34.) also known as callose synthase catalyses the formation of a beta-1,3-glucan polymer that is a major component of the fungal cell wall. The reaction catalysed is:-UDP-glucose + {(1,3)-beta-D-glucosyl}(N) = UDP + {(1,3)-beta-D-glucosyl}(N+1).

Class A
1,3-Benzodioxolylbutanamine (also known as 3,4-methylenedioxybutanphenamine, MDB, BDB, J, and 3,4-methylenedioxy-α-ethylphenethylamine) is an entactogenic drug of the phenethylamine chemical class. It is the α-ethyl analog of MDPEA and MDA and the methylenedioxy analogue of α-ethylphenethylamine.BDB was first synthesized by Alexander Shulgin. In his book PiHKAL (Phenethylamines i Have Known And Loved), the dosage range is listed as 150–230 mg and the duration is listed as 4–8 hours. BDB produces entactogenic, MDMA-like effects. While pleasant and euphoric, BDB is also fairly sedating and some users feel that the lack of stimulant effect makes it less enjoyable than other similar drugs. Additional side effects associated with BDB include nystagmus and dizziness. Very little data exists about the pharmacological properties, metabolism, and toxicity of BDB.Animal studies and anecdotal reports show that BDB is a slightly more potent serotonin releasing agent than its methylated sister compound methylbenzodioxylbutanamine (MBDB; "Eden", "Methyl-J"). However, it is more commonly known as a metabolite of the N-alkylated analogues MBDB and ethylbenzodioxylbutanamine (EBDB; "Ethyl-J") which have appeared in methylenedioxymethamphetamine (MDMA; "Ecstasy", "Adam", "Empathy", "Molly", "E", "X", "XTC") tablets. While BDB itself has not been reported as being sold as "Ecstasy", urine analysis of "Ecstasy" users suggest that this drug may have appeared as a street drug, although it is unclear whether the positive urine test for BDB resulted from consumption of BDB itself or merely as a metabolite of MBDB.

The 1,3-dipolar cycloaddition is a chemical reaction between a 1,3-dipole and a dipolarophile to form a five-membered ring. The earliest 1,3-dipolar cycloadditions were described in the late 19th century to the early 20th century, following the discovery of 1,3-dipoles. Mechanistic investigation and synthetic application were established in the 1960s, primarily through the work of Rolf Huisgen. Hence, the reaction is sometimes referred to as the Huisgen cycloaddition (this term is often used to specifically describe the 1,3-dipolar cycloaddition between an organic azide and an alkyne to generate 1,2,3-triazole). Currently, 1,3-dipolar cycloaddition is an important route to the regio- and stereoselective synthesis of five-membered heterocycles and their ring-opened acyclic derivatives.
