Serinolamide A, isolated from a species of marine cyanobacteria, exhibits a moderate agonist effect and selectivity for the CB1 cannabinoid receptor, which is unusual for marine natural products. Herein, we reported a highly efficient enantiospecific first total synthesis of (+)-serinolamide A from l-serine in nine steps with 30% overall yield. The synthesis method provides a facile, practicable, and economical approach for the preparation of other similar endocanabinoid lipids.

The synthesis and biological evaluation of azido-N-oleoyl serinol is reported. It mimicks biofunctional lipid ceramides and has shown to be capable of click reactions for cell membrane imaging in Jurkat and human brain microvascular endothelial cells.

, p. 33 - 37 (2015/01/30)
The synthesis of Yanglingmycin and its enantiomer, along with eighteen Yanglingmycin analogues is reported. The structures were confirmed mainly by analyses of NMR spectral data. Antibacterial activity assays showed that Yanglingmycin and some of its analogues exhibited significant antibacterial activities against two important agricultural pathogenic bacteria, Ralstonia solanacearum and Pseudomonas syringae pv. actinidiae, with minimum inhibitory concentration (MIC) values ranging from 3.91 to 15.62 μg/mL. The antibacterial activities exhibited by Yanglingmycin and its analogues are promising, suggesting potential in the development of compounds for novel bactericides.
I2-Catalyzed C-O Bond Formation and Dehydrogenation: Facile Synthesis of Oxazolines and Oxazoles Controlled by Bases
Gao, Wen-Chao,Hu, Fei,Huo, Yu-Ming,Chang, Hong-Hong,Li, Xing,Wei, Wen-Long
supporting information, p. 3914 - 3917 (2015/08/18)
A general method for the synthesis of oxazolines and oxazoles was developed through I2-catalyzed C-O bond formation and dehydrogenation with the same oxidant, TBHP. By simply tuning reaction bases, either oxazolines or oxazoles were selectively
Synthesis of protected α-alkyl lanthionine derivatives
Deno?l, Thibaut,Zervosen, Astrid,Lemaire, Christian,Plenevaux, Alain,Luxen, André
, p. 4526 - 4533 (2014/06/10)
Protected α-alkyl lanthionine derivatives were synthesized in five steps starting from a known phenyloxazoline precursor. This approach involved the synthesis of a family of substituted cyclic sulfamidates and their regioselective opening by nucleophilic attack with a protected cysteine. This efficient multistep strategy affords various α-alkylated lanthionine derivatives in high yields.
Pd(ii)-catalyzed direct C5-arylation of azole-4-carboxylates through double C-H bond cleavage
Li, Ziyuan,Ma, Ling,Xu, Jinyi,Kong, Lingyi,Wu, Xiaoming,Yao, Hequan
, p. 3763 - 3765 (2012/06/15)
The first palladium-catalyzed direct C5-arylation of azole-4-carboxylates with simple unactivated arenes through double C-H bond cleavage is realized. This protocol provided a straightforward access to diverse 5-arylsubstituted azole-4-carboxylic derivatives with good functional group tolerance. The Royal Society of Chemistry 2012.

The preparation of 2-oxazolines and related N-containing heterocycles from the corresponding hydroxyamides using XtalFluor-E ([Et2NSF 2s]BF4) as a cyclodehydration agent is described. A wide range of heterocycles are obtai
Catalytic asymmetric hydrogenation of N-Boc-imidazoles and oxazoles
Kuwano, Ryoichi,Kameyama, Nao,Ikeda, Ryuhei
experimental part, p. 7312 - 7315 (2011/06/24)
Substituted imidazoles and oxazoles were respectively hydrogenated into the corresponding chiral imidazolines and oxazolines (up to 99% ee). The highly enantioselective hydrogenation was achieved by using the chiral ruthenium catalyst, which is generated

The use of phosphonium anhydrides for the synthesis of 2-oxazolines, 2-thiazolines and 2-dihydrooxazine under mild conditions
Petersson, Maria J.,Jenkins, Ian D.,Loughlin, Wendy A.
experimental part, p. 739 - 746 (2009/06/20)
β-Hydroxy amides 6 and 7 were treated with triphenylphosphonium anhydride trifluoromethane sulfonate (3), or the cyclic analogue 4, to generate 2-oxazolines 5 and 8 under mild conditions. The reaction was optimised by examining the number of equivalents of reagents 3 or 4, or diisopropylethyl amine required to best effect cyclisation. The effects of altering the reaction temperature, reaction time, concentration, solvent, and addition rate also were investigated. However, it was found that use of a trityl group to block reaction at the hydroxyl or thiol group of the starting amides, and subsequent in situ detritylation, in the absence of base, led to greatly improved yields. Reagent 4 offered significant advantages in the purification of products and was used to dehydrate a range of trityl derivatives to form simple oxazolines, thiazolines, and a dihydro-1,3-oxazine, in high yield (85-99%), as well as a tetrahydro-1,3-oxazepine (31%).
