“…In order to better predict the outcomes and rationally design photochemical syntheses, a broader understanding of functional group behavior is needed. Organic sulfides, sulfoxides, and sulfones are common functional groups relevant to pharmaceutical,3 agrochemical,4 and light‐emitting compounds 5. The photochemistry of various alkyl and aryl sulfoxides has been examined by Lee and Jenks with a focus on the mechanism of pyramidal inversion at sulfur 6.…”

“…Impressively, 85 can be obtained by heterocyclization from six altogether different acyclic starting materials: 3-amino2-chlorpropene (81), propargylamine (83), N-(2-chloro-2-propenyl)formamide (84), allyl isothiocyanate (86), 2,3-dichloropropene (89) and 1,3-dichloropropene (90) very inexpensive reagents, such carbon disulfide, chlorine, sulfur chloride and sodium hydroxide (Scheme 9). 60,61 In conclusion, heterocycles play an important role in the control of weeds, insects and fungal diseases. Their structural diversity is impressive, as is the wide range of different modes of actions involved.…”

An overview is given of the significance of heterocycles in crop protection chemistry, which is enormous as more than two-thirds of all agrochemicals launched to the market within the last 20 years belong to this huge group of chemicals. This review focuses on two important aspects of heterocyclic agrochemistry: the different roles of heterocyclic scaffolds in crop protection agents and the major possibilities for their synthesis.

“…In general, combining one pharmacophore with others leads to the formation of new molecular scaffolds with improved biological functions. Further, sulfur-heterocycles are highly pursued synthetic targets due to their limited availability from natural sources [38][39][40].…”

One-pot synthesis, biological evaluation, and docking study of new chromeno-annulated thiopyrano[2,3-c]pyrazoles

A one-pot synthesis of new chromeno-annulated thiopyrano[2,3-c]pyrazoles has been achieved through a domino-Knoevenagel-hetero-Diels-Alder reaction after combining various pyrazol-5-thiones with O-alkenyloxy/alkynyloxy-salicylaldehydes/naphthaldehydes in a Brønsted acidic ionic liquid, [Hmim]HSO[Formula: see text], methylimidazolium hydrogen sulphate, under microwave irradiation. The method is simple and in many cases the isolated products did not require further purification. The central pyranothiopyranyl cis-fusion was confirmed by 2D NMR NOESY and single-crystal X-ray analysis suggesting that the endo-E-Syn transition state would be the most favored pathway of the reaction. Many heterocycles of this new series were found active against six bacterial and two fungal strains. In addition, all the compounds possess good anti-oxidant activity with the ferric reducing anti-oxidant power value [Formula: see text]. All new structures were docked into active site of angiotensin I converting enzyme (ACE), assuming that the compounds possessed the anti-hypertensive activity potential on the basis of prediction of activity spectra of substances prediction results. Pyranyl ring oxygen in compound 9a forms two hydrogen bonds with HIS353 and HIS513 residues in the active site of the ACE having good G score ([Formula: see text]) of this compound, comparable to that of the reference drug captopril ([Formula: see text]).
