3-tert-Butyl-2-oxo-1-oxaspiro[4.5]dec-3-en-4-yl 4-chlorobenzoate
The title tetronic acid derivative, C(20)H(23)ClO(4), which is a spiro-diclofen analogue, has two crystallographically independent mol-ecules in the asymmetric unit (Z' = 2). The cyclo-hexane rings in the respective mol-ecules A and B adopt chair conformations [four C atoms are planar with mean deviations of 0.013 (2) and 0.001 (2) Å, and the flap positions deviate by 0.653 (4) and -0.663 (3) Å...
متن کاملtert-Butyl 5-(4-methoxyphenyl)-1-methyl-2-oxopyrrolidin-3-yl carbonate
In the title compound, C(17)H(23)NO(5), the pyrrolidinone ring is in an envelope conformation. The tert-butyl carbonate and 4-methoxy-phenyl groups are arranged on the same side of the pyrrolidinone ring. The meth-oxy group is coplanar with the attached benzene ring. The mol-ecules are linked into chains along the b axis via C-H⋯O hydrogen bonds.

In the title compound, C(19)H(22)F(3)NO(4), the dihedral angle between the benzene ring and the conjugated part of the enaminone ring is 42.5 (1)°. The ester substituent makes a dihedral angle of 81.3 (2)° with this latter moiety. The crystal structure is held together by strong N-H⋯O and weak C-H⋯O inter-molecular inter-actions. The enaminone ring is disordered over two orientations with relat...
متن کامل5-tert-Butyl-2-[5-(5-tert-butyl-1,3-benzoxazol-2-yl)-2-thienyl]-1,3-benzoxazole
The title compound, C(26)H(26)N(2)O(2)S, was prepared by the reaction of thio-phene-2,5-dicarboxylic acid and 2-amino-4-tert-butyl-phenol. One of the tert-butyl groups is disordered over two conformations, with occupancies of 0.539 (1) and 0.461 (2). The two 1,3-benzoxazole rings are almost planar, with dihedral angles of 0.83 (18) and 1.64 (17)° between the five- and six-membered rings. The th...
