The characteristic features of hydrolysis of diaryl phosphate monoanions (pronounced influence of leaving group on the rate of hydrolysis, k o/k = 1.6, and AS = —25 euu7y) also fail to support a metaphosphate mechanism118>. Hydrolysis of the acetyl phenyl phosphate monoanion is likewise far slower than that... [Pg.111]

Aroylcoumaran-3-ones (61) can also be synthesized from the Baker Venkatraman rearrangement of 2-[(tosyloxy)acetyl]phenyl benzoates with potassium hydroxide (920PP469, 92S629). [Pg.20]

This methodology is valuable for similar derivatives in the D-manno [68], L-ara-bino [69] and 2-deoxy or 2,3-deoxy [70] series. Parallel work [71] on the O-formyl and O-acetyl phenyl P-D-glucopyranoside 70 and its a-anomer 71 yield compounds 72 and 73. The epimerization of 72 in acidic conditions leads to the more stable compound 73 by anomeric effect. Stereoelectronic effects can explain the twist-boat conformations of 69 and the chair conformation for the manno analog established by x-ray cristallography [72-73]. [Pg.63]

A tellurium-triggered cyclization of methyl 2-(2-bromoacetoxy)benzoates 671 affords 4-hydroxy coumarins in good yield (Scheme 160) <2005JOC4682>. Similarly, the tellurium-triggered cyclization of 2-formyl and 2-acetyl-phenyl 2-bromoacetates 672 provides coumarins (Equation 271) <2005JOC4682>. [Pg.559]

Flavanols are similarly accessed from 2-(2-(benzoyloxy)acetyl)phenyl benzoates 752 via a Baker-Venkataraman rearrangement to form 3-benzoyloxy flavones followed by deprotection of the hydroxyl group (Scheme 194) <2000JOC583>. 3-Aroyl flavones are prepared form or/ o-hydroxyacetophenones and aroyl chlorides in modest yield, using a Kostanecki-Robinson approach (Equation 305) <2005SC315>. [Pg.581]

Even though it is generally admitted that both the reaction temperature and the substrate/AA ratio have a positive effect on the production of acetylated phenyl ethers,[3] there are no papers describing the effect of temperature and in only one study is the effect of the anisole/AA ratio in fixed bed reactor experiments described.191 At 363 K, for a contact time x > 0.05 h (t is taken as the inverse of the weight hour space velocity for anisole), anisole is almost completely acetylated initially [time on stream (TOS) of 10 min] when anisole/AA is 5, whereas less than 50 % of anisole is transformed with an equimolar ratio. Moreover with higher ratio... [Pg.80]

Oxo-2,3-dihydrobenzo-l-tellurophene was converted by hydrogen cyanide to 2-acetyl-phenyl tellurium cyanide3. [Pg.369]

Benzylidene-3-oxo-2,3-dihydrobenzotellurophenes were also obtained when 2-acetyl-phenyl tellurium bromide and aromatic aldehydes were refluxed in acetic acid in the presence of piperidine. 3-Oxo-2,3-dihydrobenzotellurophene could be the intermediate that condenses with the aldehydes1. [Pg.757]

Furthermore, the choice of enyne substrates can lead to cyclized products that contain other functionalities than dienes. Very recently, Muller and Kressierer [148] have shown that yne allyl alcohols 200 can be rapidly cyclo-isomerized by a Pd2dba3-W-acetyl phenyl alanine catalyst system to furnish heterocyclic enals 202 in excellent yields (Scheme 82). The intermediate product of the enyne cycloisomerization in this case is the enol 201, which rapidly tautomerizes to the aldehyde 202. [Pg.193]
