The reaction of isocyanates with enamines disubstituted at the -carbon gives -amino- -lactams (107,108). Thus the enamine (16) reacted exothermally with phenylisocyanate to give (33) dimethyl-l-phenyl-4-dimethylamino-2-acetidinone (157), which was converted by acid hydrolysis to 2-formyl-2-methyl propionanilide (158). 

The Reimer-Tiemann reaction has also been used to formylate 2,5-dimethylpyrrole and its iV-methyl derivative and indoles having methyl, methoxyl, and phenyl substituents. Significantly, 3-methylindole gave only 3-chloro-4-methylquinoline. ...

The reaction with disubstituted formamides and phosphorus oxychloride, called the Vilsmeier or the Vilsmeier-Haack reaction,is the most common method for the formylation of aromatic rings. However, it is applicable only to active substrates, such as amines and phenols. An intramolecular version is also known.Aromatic hydrocarbons and heterocycles can also be formylated, but only if they are much more active than benzene (e.g., azulenes, ferrocenes). Though A-phenyl-A-methyl-formamide is a common reagent, other arylalkyl amides and dialkyl amides are also used. Phosgene (COCI2) has been used in place of POCI3. The reaction has also been carried out with other amides to give ketones (actually an example of 11-14),... 

No compound other than the methyl ester of N-benzoyl-Lphenylalanine, 33, is an obvious choice for an open-chain analog of the locked substrate 25 but D-24, on the other hand, may be a locked analog of either N-benzoyl-D-alanine methyl ester 34 or of N-formyl-D-phenylalanine methyl ester 35 (75). If 24 is an analog of 34 rather than 35, the comparison of the two locked analogs made in Section V.B. is not valid the phenyl of 24 would then correspond to the benzoyl phenyl of 34.

Similarly l-phenyl-3-methyl-4-formyl-5-chloropyrazole reacts with thioglycollic acid in the presence of alkali to yield a mercaptopyrazole derivative that could be cyclized to thieno[2,3-c]pyrazole in the presence of alkali (69KGS760, 69ZOR1498). Similar to this is the reported formation, via 311, of 312 from 310 and mercaptoacetanilide (73ZOR2416).
