A few additional Pd-catalyzed schemes have been employed for Ilac type cyclization chemistry. Palladium-phenanthroline complexes were used by the Ragaini group to prepare indoles via the intermolecular cyclization of nitroarenes and alkynes in the presence of carbon monoxide <06JOC3748>. Jia and Zhu employed Pd-catalysis for the annulation of o-haloanilines with aldehydes <06JOC7826>. A one-pot Ugi/Heck reaction was employed in the preparation of polysubstituted indoles from a four-component reaction system of acrylic aldehydes, bromoanilines, acids, and isocyanides <06TL4683>.

The types of dienophiles which have been studied most are acrylic aldehydes, acrylates and 3-acryloyl-l,3-oxazolidines. The latter have been used predominantly in copper, magnesium, zinc and lanthanide catalyzed reactions in which the chiral Lewis acid binds in an rj2 fashion to the dienophile (complexation to both carbonyls). 

Yamamoto and colleagues showed that very high enantioselectivities and yields were obtained in the cycloadditions of cyclopentadiene with several a-substituted acrylic aldehydes using binaphthol catalyst 387 (equation 116).

Though thioacetone polymerizes spontaneously, by free-radical initiation, and by base initiation, it does not form copolymers in any of these systems. Efforts to obtain copolymers with dienes, vinyl compounds, acrylates, aldehydes, and epoxides have failed. 

The second synthesis of 654 and 655 makes use350,351 of the Wittig reaction. The (methylthio)methyl ether 656 is converted into the chloromethyl ether 657, which reacts with triphenylphosphine to yield a crystalline phosphonium salt (658). Reaction of 658 with phenyllithium gives a phosphorane, treatment of which with acryl-aldehyde leads to ethers 654 and 655 in —50% yield. Pure trtms-diene 654 was obtained352 in a reversed way consisting in preparation of a sugar ether acrylaldehyde (660) by replacement of the p-tolylsulfonyl group in 659, followed by reaction of 660 with methylenetriphenyl-phosphorane.

Peptidomimetics in which one amide bond is replaced by a phosphinic acid (R-P(0H)(=0)-R phosphinic peptides ) are of interest as potential protease inhibitors [17-19]. These compounds have been prepared either from orthogonally protected phosphorus-containing monomers [17,18,20], or by forming the phosphorus-containing fragments on solid phase, as sketched in Figure 11.4 [19,21], Phosphinic acids have been prepared on solid phase mainly by reaction of carbon electrophiles with monoalkylphosphinates. As carbon electrophiles, acrylates, aldehydes, reactive alkyl halides, or a, 3-unsaturated ketones can be used. 

Formaldehyde, acetaldehyde, acetone, and carbon monoxide were common combustion products of the four hexanes. Propionaldehyde, n-butyraldehyde, acrylic aldehyde, crotonic aldehyde, and methyl ethyl ketone were all found as intermediates in the combustion of n-hcxane. Acetaldehyde and acetone were prominent and propionaldehyde and acrylic aldehyde were present among the intermediates from 2-methylpentane. Acetaldehyde and methyl ethyl ketone were peculiarly characteristic of 3-methyl-pentane and acetaldehyde, acetone, and pivalic aldehyde were characteristic of 2,2-dimethylbutane. In other words, the intermediate monocarbonyl combustion products... 

ICD mediated the addition of aryl methylbenzenesulfonamides, such as 105, to ethyl or methyl vinyl ketones in MeCN DMF (1 1) mixtures at a lower temperature (—30 °C) [95a]. The reaction afforded products with (R) absolute configuration (Table 5.13). Of note, this situation was opposite to that observed in the related aza-MBH reaction with acrylonitrile with acryl aldehyde or with acrylates. Related N-mesyl or N-SES-protected imine afforded similar results.
