Abstract: alpha -(o-Chlorophenyl)-aminomethylene- beta -formylaminopropionitrile, process for its preparation by reacting a metal salt of alpha -formyl- beta -formylaminopropionitrile with a salt of o-chloroaniline in an aqueous medium, and use of the product to prepare the compound of the formula by reaction with acetamidine. The pyrimidine thus obtained is an intermediate for the preparation of vitamin B1.

Abstract: of the disclosure: 3-Chloro-3-methyl-butane-1,4-dial-bis-acetals and 3-methyl-but-2-ene-1,4-dial-bis-acetals are obtained by reacting a six-membered cyclic acetal of 3-methyl-but-3-en-1-al with an alkyl nitrite in the presence of methanol and hydrogen chloride and, if desired, eliminating HCl in the conventional manner. The butan-dial-bis-acetals and butenedial-bis-acetals are valuable intermediates through which the trans-3-methyl-but-2-ene-1,4-dial-1-ecetals, which are sought-after products for terpene syntheses, can be obtained in an industrially particularly advantageous manner.

Abstract: Preparation of N-acyl derivatives (I) using readily available starting materials. N-acyl derivatives of formula R -C(O)N(H)C(R )X (I) are prepared by reacting, in the presence of a compound of formula R -COOH (II), a carbonic acid amide of formula R -CONH2 (III) and a glyoxalmonoacetal derivative of formula R C(O)C(OR )OR (IV). R , R = H or optionally substituted alkyl or aryl; R ,R = 1 - 12C alkyl; and X = CH(OR ) or COOR . An Independent claim is also included for a compound of formula R -C(O)N(H)C(R )C(OR )OR (V).
