Acetic acid derivatives of the formula ##STR1## wherein L, M, T and Q have the significance given in the description, can be used for the treatment or prophylaxis of illnesses which are caused by the binding of adhesive proteins to blood platelets and by blood platelet aggregation and cell-cell adhesion, and are manufactured by cleaving protecting groups in the corresponding protected compounds or by converting the cyano group into the amidino group in corresponding nitriles.

pure bicyclic cyclobutanones. The cycloadditions proceeded with unusual regiochemistry giving predominantly or exclusively protected α-amino-β-hydroxycyclobutanone derivatives. The adducts could be converted into a variety of interesting enantiopure intermediates equipped with many functional groups: α-amino-β-hydroxy cyclopropane carboxylicacid derivatives, α-amino-β-hydroxy succinic acid derivatives
