1. l-Serine methyl ester hydro-chloride
Arie Schouten, Martin Lutz Acta Crystallogr Sect E Struct Rep Online. 2009 Nov 7;65(Pt 12):o3026. doi: 10.1107/S1600536809046480.
In the enanti-opure crystal of the title compound, C(4)H(10)NO(3) (+)·Cl(-), inter-molecular O-H⋯Cl and N-H⋯Cl hydrogen bonds link the mol-ecules into layers parallel to (001).
2. Asymmetric Total Synthesis of Griseofamine B and Its Three Stereoisomers
Tao Sheng, Caiyun Ma, Guangyan Zhang, Xuan Pan, Zhanzhu Liu J Nat Prod. 2022 Apr 22;85(4):1128-1133. doi: 10.1021/acs.jnatprod.2c00069. Epub 2022 Mar 3.
The first total synthesis of griseofamine B is described starting from l-4-bromo tryptophan methyl ester hydrochloride via five steps and in 18% overall yield. Its three stereoisomers were also synthesized following the same procedure with the yields of 5%, 19%, and 5%, respectively. In vitro antibacterial activities were also evaluated. All four compounds exhibited less potent activity than griseofamine A.
