Phenoxy phenyl

Chloro-5-phenyl-1,2-dithiolium chloride reacts with phenol not only at the para carbon atom (see Section II,B,7,c) but also at the hydroxyl, to give the unstable 3-phenoxy-5-phenyl-1,2-dithiolium chloride, easily hydrolyzed to the corresponding l,2-dithiol-3-one (Scheme 14). ...

The search for other amino acid-based catalysts for asymmetric hydrocyanation identified the imidazolidinedione (hydantoin) 3 [49] and the e-caprolactam 4 [21]. Ten different substituents on the imide nitrogen atom of 3 were examined in the preparation, from 3-phenoxybenzaldehyde, of (S)-2-hydroxy-2-(3-phenoxy-phenyl)acetonitrile, an important building block for optically active pyrethroid insecticides. The N-benzyl imide 3 finally proved best, affording the desired cyanohydrin almost quantitatively, albeit with only 37% enantiomeric excess [49]. Interestingly, the catalyst 3 is active only when dissolved homogeneously in the reaction medium (as opposed to the heterogeneous catalyst 1) [49]. With the lysine derivative 4 the cyanohydrin of cyclohexane carbaldehyde was obtained with an enantiomeric excess of 65% by use of acetone cyanohydrin as the cyanide source [21].

In subsequent investigations by others, Step 7 piperidine- and tetrahydro-2H-thiopyran-sulfonyl derivatives were prepared. These include l-cyclopropyl-N-hydroxy-4-[[4-[4-( 1 -ethylethoxy)-phenoxy] -phenyl]-sulfonyl] -4-piperidinecarboxamide hydrogen chloride, (III), (3) and tetrahydro-4-[[4-trifluoromethyloxy)-phenyl]sulfonyl]-2H-thiopyran-4-carboxamide, (IV), (4). 

The majority of pyrethroid insecticides have low volatilities. The heavily used synthetic pyrethroid permethrin is classified as nonvolatile on the basis of its vapor pressure (1.3 x 10 kPa at 20 °C) and is rarely found in indoor air. However, it has recently been reported to be the major pesticide residue found in house dust (USEPA, 2000d). Cyper-methrin [( )-a-cyano-3-phenoxybenzyl-( )-cA,frani -3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate] and cyfluthrin [cyano(4-fluoro-3-phenoxy-phenyl)methyl 3-(2,2-dichloro-ethenyl)-2,2-dimethylcyclopropanecarboxylate] are two other low-volatility pyrethroids commonly used for indoor flea and cockroach control. 

Trisubstituted thyronine analogs have been studied using EHT to predict the phenoxy phenyl conformation as influenced by the 3,5-substituents (Figure 16) (53). EHT predictions indicated that 3,5-iodo and 3,5-bromo groups influenced a preference as shown in Figure 16, in agree-...
