The Preparation and Deamination of 1-t-Butyl-3-amino-, 1-t-Butyl-3-aminomethyl-, and 1-t-Butyl-2-aminomethylazetidine

1-Butyl-3-(1-naphtho­yl)-1H-indole

In the title mol-ecule, C(23)H(21)NO, the dihedral angle between the planes of the indole ring and naphthalene ring system is 68.8 (5)°.

1-(3-tert-Butyl-4-hy­droxy­phen­yl)ethanone

The title compound, C(12)H(16)O(2), is approximately planar (r.m.s. deviation = 0.030 Å), apart from two methyl groups of the tert-butyl unit [deviations of the C atoms = 1.140 (2) and -1.367 (1) Å]. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into hexa-meric rings with R(6) (6)(48) graph-set motifs.

3-tert-Butyl-1H-isochromene-1-thione

The title compound, C(13)H(14)OS, crystallizes with two independent mol-ecules in the asymmetric unit. The unit cell contains three voids of 197 Å(3), but the residual electron density (highest peak = 0.24 e Å(-3) and deepest hole = -0.18 e Å(-3)) in the difference Fourier map suggests no solvent mol-ecule occupies this void. The crystal structure is stabilized by π-π inter-actions between the ...

tert-Butyl (2S)-2-{3-[(R)-bis­(tert-but­oxy­carbon­yl)amino]-2-oxopiperidin-1-yl}-3-methyl­butano­ate1

The title compound, C(24)H(42)N(2)O(7), is a chiral lactam-constrained amino acid with a six-membered ring backbone and isopropyl and tert-butyl ester side chains. The conformation of the six-membered ring can be described as a half chair, with two CH(2) C atoms lying 0.443 (1) and -0.310 (1) Å out of the best plane of the other four atoms (mean deviation = 0.042 Å). Both N atoms are sp(2) hybr...
