The smino acids used hy Blicke and Gould -were all secondary amines obtained by the addition of benzylamiue or alkyl amines to atropic acid or other substituted acrylic acids. The acid chloride salts v ore prepared by treatment with thionyl chloride, and after removing by-products the crude products were r cxed in bensene solution with excess dimethylaniline. The 1.8- and 1,4-disuhstituted azetidinones were isolated in yields of 40 80%, The benefioial influenoe of substitution was observed with the l-benzyl-S-methyl 4-phenyl- and l-benxyl-.S,3-dim thyl-4 phenyl-2-azetidinones, both of which were obtained in 90% yield. In an unsbooeasfu) attempt to prepare -aminodiasoketonea several of the acid chloride hydrochlorides were treated with diaxo-methane this reaction also fumishes the /9-laotams, although in rather low yield. 

Heating a 3-(2-hydroxyphenyl)propionate ester in diphenyl ether with palladium-charcoal induces a combined cyclization and dehydrogenation [3437], Simultaneous de-O-benzylation and cyclization of a 2-(benzyloxy)acrylic acid by heating with acetyl chloride containing phenyltrimethylammonium iodide gives good yields of a fused pyran-2-one [3836]. In contrast, an o-methoxy-benzylidenemalonic acid (as its potassium salt) cyclizes in the cold when treated with trifluoroacetic acid-trifluoroacetic anhydride [3938].

IGC was also use to elucidate the nature of the interaction of both reactives and products with the surface of heterogeneous catalysts in order to obtain information for understanding the mechanism of the reaction. Xie et al. [31] proposed a mechanism for the partial oxidation of propylene to acrylic acid based on the adsorption parameters of reactive and products on styrene divinylbenzene copolymer (SDB) and Pd supported on SDB. Likewise, Dfaz et al. [53] studied the performance of Fe-ZSM-5 catalysts for benzylation of benzene with benzyl chloride in terms of their chemical and adsorption properties. 

Abell et al. [288] reported the reaction of 5-formyl-lH-pyrrole-2-carboxylic amides bound to the polymeric support via their amide linkage (249) and dihydrocinna-moyl chloride. The acid chloride is believed to acylate the pyrrole nitrogen prior to an intramolecular Knoevenagel type condensation. The resulting bicycle (251) is deeply colored and was suggested by the authors to be used as a tag for combinatorial libraries. Upon treatment with NaOCHs, the bicycHc structure can be reverted to a 1-benzyl 3-pyrrolyl acrylic ester (Scheme 55). 

Successful polymer supported stereoselective Diels-Alder reaction was performed using immobilized enantiopure 4-(3-hydroxy-4,4-dimethyl-2-oxopyrro-lidin-l-yl)benzoic acid 12 as a chiral auxiliary [15]. The corresponding resin-bound acrylate derivate has been applied as the dienophile 13. Preparation of the precursor started with the combination of pantolactone 10 and the sodium salt of 4-aminobenzoic acid. Conversion into the corresponding benzyl ester followed. The obtained racemate was esterified with (lS)-camphanic acid chloride to a dia-stereomeric mixture to gain the enantiopure compounds by chromatographic separation. After subsequent saponification of the camphanic acid moiety and hydrolysis of the benzyl ester the (R)-enantiomer 11 was coupled to Rink amide resin (Scheme 12.6). 

A solid-phase submonomer approach to A-substituted j8-aminopro-pionic acid oligomers or )8-peptoids has been developed by Hamper et al. [63]. It is based on a simple two-step acylation and Michael addition reaction sequence. Treatment of Wang resin with 2 equiv. of acryloyl chloride in the presence of triethylamine in excess afforded the corresponding acrylate resin 86 (Scheme 23) [63]. Michael addition of a 6- to 10-fold excess of a given primary amine in DMSO afforded polymer-bound A-substituted -alanines (87). Trimeric A-benzyl-j8-aminopropionic acid (88) was prepared in 67% overall yield by repetition of this two-step sequence.
