Source of material
Pivalic anhydride (4.36 g, 20 mmol) was added to an ice-cooled solution of S-(+)-alaninol (1.50 g, 20 mmol) and triethylamine (2.78 ml, 20 mmol) in tetrahydrofuran (60 mL). The mixture was warmed to room temperature, stirred for 90 minutes and concentrated in vacuo. The residue was dissolved in ethylacetate (50 mL), washed twice with 50 mL of water, brine (50 mL), dried with Na2SO4 and concentrated in vacuo to afford the title compound (3.46 g, yield > 90%) as a colourless, crystalline solid [5, 6] .
Experimental details
All hydrogen atoms were positioned geometrically, allowed to ride on their parent atoms and refined isotropically. The absolute structure was determined by refinement of the Flack parameter (0.10(15) [2]) using Parsons method [4].
Discussion
Protection of amines, amino acids and amino alcohol with a tert-butyloxycarbonyl (Boc) group can be conducted under aqueous or anhydrous condition, using a base and anhydrous Boc2O. N-Protected amino alcohols are versatile building blocks in organic synthesis and have many applications in the synthesis of important chemicals and pharmeceuticals. We have reported one of the application of Boc protected alaninol derivatives previously [5], [6], [7].
The crystal structure of the title compound contains two symmetrically non-equivalent molecules in the asymmetric unit. Each molecule consists of a tert-butoxy unit and a N-[2-hydroxy-1-methylethyl]amidyl moiety, which confirms the successful synthesis of the title compound. The two molecules also have of a stereogenic centre with S-configuration at C2 in one molecule and C10 in the other (cf. the figure). Classical intermolecular N—H⋯O hydrogen bonding is observed between the amide hydrogen atoms and carbonyl oxygen atoms (N1⋯O2′ = 2.977(2) Å; ′= −x + 1, y − 1/2, −z + 1; N2⋯O5′′ = 3.047(2) Å; ′′= −x + 1, y + 1/2, −z) of neighbouring molecules. Linking in this manner forms chains, which extent along the b axis. The OH groups are involved in classical O—H⋯O hydrogen bonding with carbonyl oxygen atoms (O1⋯O5 = 2.800(2) Å) and OH groups (O4⋯O1′′ = 2.855(2) Å) of neighboring molecules. The O—H⋯O hydrogen bonding patterns sew the chains together resulting in a two dimensional network. All bond lengths and angles are in the expected ranges for this class of compounds [8].
