  • Cyclic nitromethyl acetic acid derivatives
    Patent number: 6911555
    Abstract: The invention provides salts of formula (I) wherein X is a basic counterion selected from a group I or group II metal and a primary, secondary or tertiary amine; n is 0, 1 or 2; and R1, R1a, R2, R2a, R3, R3a, R4 and R4a are independently selected from H and C1-C6 alkyl, or R1 and R2 or R2 and R3 are taken together to form a C3-C7 cycloalkyl ring, which is optionally substituted with one or two substituents selected from C1-C6 alkyl, which are useful as intermediates in the preparation of cyclic and bicyclic amino acids. Processes for the preparation of the final products and for the conversion of the compounds of formula (I) to amino acids are included.
