R5 (III) in which R* and R5 are as defined above and R8, R9 and R10 are identical or different aryl radicals, preferably phenyl.
To prepare a compound of the formula Ila or lib, suitably 10 protected amino acid derivatives can be used as starting materials. These yield Ila or lib as a result of double reaction with the nucleophilic formyl equivalent 2trimethylsilylthiazole TST (Scheme 1) (A. Dondoni et al.,
J. Org. Chem. 1990, 55, 1439) in a solvent which is inert to this nucleophile such as diethyl ether, di-n-butyl ether, MTB, dichloromethane, DIP, THF, tetrahydropyran or DME at a temperature between -40 °C and the boiling point of the solvent, preferably between -40°C and +25°C. The first addition of TST takes place with high syn selection, the second with high anti selection. The resultant hydroxyl function is protected in the next reaction step using methods known from the literature. The liberation of the formyl group can be carried out by the following reaction sequence:
1) N-Alkylation with a suitable alkylating reagent such as, for example, dimethyl sulfate or methyl iodide without solvent or in a suitable inert solvent such as, for example, acetonitrile, THF, MTB, DIP or EA at temperatures between 25°C and the boiling point of the appropriate solvent.
2) Reduction using a hydride transfer reagent such as, for example, NaBH4 in a solvent suitable for these types of reaction such as, for example, methanol or ethanol at temperatures between -30C and 25 “C, preferably between -20 °C and O’C.
3) Liberation of the aldehyde group by action of reagents for the cleavage of thioacetals (see Tamura et al., Synthesis 312 (1973), Seebach et al., ibid. 357 (1977) and literature cited therein), preferably by means of N-bromosuccinimide in a mixture of acetone and water, preferably at O’C to 30’C.

The Wittig reaction with a suitable phosphorane in an inert solvent such as diethyl ether, di-n-butyl ether, MTB, DIP, THF, DME or dioxane at -30°C up to the boiling point of the solvent, preferably between O’C and 30’C, yields the title compounds of the formula la or lb. The aldehyde of the formula Ila or lib can also be reacted with the anion of a suitable phosphine oxide with the formation of the title compound (Horner; see Krauch, Kunz, Reaktionen der Organischen Chemie (Reactions of
Organic Chemistry), Huthig Verlag Heidelberg 1976, page 2 41).
The compounds of the formulae la and lb according to the invention are valuable intermediates for the preparation of pharmaceuticals, in particular of inhibitors of renin and of HIV protease. Inhibitors in whose synthesis these compounds can advantageously be used are described, for example, in FEBS Lett. Vol. 230, 38 (1988), J. Med. Chem. Vol. 31, 2264 (1988), ibid. 2277, Biochem.
