The synthesis of the CG525155 (a neutral endopeptidase inhibitor) required a Pd catalyzed Tsuji-Trost reaction as the key step following the strategy described by Johnson. Starting from the optically active allenyl amino acid methylester 91 (synthesized in several steps from 90), the seco-derivative 92 as the crucial precursor was generated in several steps in high yield. The Pd (0)... [Pg.140]

The variety of educts and products of the higher MCRs is illustrated here. Product 72 (Scheme 1.18) is formed from the five functional groups of lysine, benzaldehyde, and tert-butylisocyanide. The synthesis of 73 is achieved with hydrazine, furanaldehyde, malonic acid, and the isocyano methylester of acetic acid, compound 74 results from the reaction of benzylamine, 5-methyl-2-furanaldehyde, maleic acid mono-ethylester, and benzylisocyanide. ° Zhu et al. prepared a variety of related products, such as, 75, from (9-amino-methyl cinnamate, heptanal, and a-isocyano a-benzyl acetamides.

A particular fruitful way to arrays of piperazine moiety containing isocyanides has been recently described [23], This efficient, scalable, and versatile procedure comprises the simple solventless mixing of a suitable a-amino acid methylester-derived isocyanide 23 with an aliphatic amine 24 (such as a substituted piperazine), filtration and washing of the resulting precipitate. Thus the array of isocyanides 25 shown in Scheme 4 was synthesized on a multigram scale mostly derived from achiral glycine and exemplary of other amino acids as well. These piperazine... [Pg.90]

Nevertheless, one process for synthesis of the low calorie sweetener, Aspartame, which is a methyl ester of a dipeptide, (Asp-Phe-OMe) involves a biocatalytic step. Aspartic acid amino protected by benzyloxycarboi rl group, is reacted with two moles of phenylalanine methylester catalysed by the protease thermolysin. The extra mole of ester makes the dipeptide precipitate and it is later recycled. For details see section 4.6. [Pg.29]

Die Synthese von 2-Amino-1,3,4-oxadiazolen aus Thiokohlensaure-(2-acyl-hydrazid)-amiden fiber Thiokohlensaure-(2-acyl-hydrazid)-imid-methylester hat trotz teilweise sehr guter Ausbeu-ten keine generelle praparativc Bedeutung. Nachteilig ist nicht nur eine zusatzliche Reaktions-stufe, sondern auch die unangenehme Methanthiol-Eliminierung. [Pg.578]
