• Description: (+)-Menthol is a monoterpene alcohol that has been found in Cannabis and has antifungal activity. It inhibits the growth of F. verticillioides (MIC = 1.5 mM). Unlike (–)-menthol, (+)-menthol does not exhibit analgesia, antibacterial, anticancer, or cholinesterase inhibitory activities.
• Uses: (1S,2R,5S)-(+)-menthol can undergo acylation with acid anhydrides in the presence of trimethylsilyl trifluoromethanesulfonate to form the corresponding acylated products. (+)-MENTHOL is used for oral gel patch or film containing herb extracts or Chinese medicine, fruit extract, spearmint, and menthol for smoking cessation.

Synthesis of enantiopure C₁ symmetric diphosphines and phosphino-phosphonites with ortho-phenylene backbones

10.1016/S0957-4166(01)00175-6

The research focuses on the synthesis of enantiopure C1 symmetric diphosphines and phosphino-phosphonites with ortho-phenylene backbones, which are valuable in asymmetric catalysis using coordination complexes of transition metals. The study utilizes various reactants, including 2-(diphenylphosphino)phenylphosphonous acid tetramethyldiamide, (+)-menthol, (1S,2S,3S,5R)-isopinocampheol, and (1R,2R)-trans-cyclohexanediol, to produce enantiopure phosphino-phosphonite ligands. The experiments involve Pd-catalyzed P–C coupling, halogen–metal exchange, and metallation–alkylation procedures. X-ray structural analysis was employed to determine the structures of the synthesized compounds, and various analytical techniques such as 31P{1H} NMR, 13C{1H} NMR, and optical rotation measurements were used to characterize the products and confirm the success of the reactions.

Toward stereoselective lactide polymerization catalysts: Cationic zinc complexes supported by a chiral phosphinimine scaffold

10.1021/ic201139b

The research focuses on the development of stereoselective lactide polymerization catalysts using cationic zinc complexes supported by a chiral phosphinimine scaffold. The main objective is to create catalysts that can operate at ambient temperature, enhancing efficiency and improving the kinetics of polymerization by reducing undesirable side reactions. The study involves the synthesis of chiral phosphinimine ligands based on the dibenzofuran (dbf) framework, specifically ligands (dbf)MePhPdNDipp (7) and (dbf)MePhPdNMes (8). These ligands are protonated with Br?nsted acids to form aminophosphonium salts, which then react with organozinc reagents to create cationic zinc complexes. The experiments utilized various reactants, including dichlorophenylphosphine, (+)-menthol, BH3, and organoazides, among others, to synthesize the ligands and their subsequent complexes. The synthesized compounds were analyzed using techniques such as NMR spectroscopy, X-ray crystallography, and elemental analysis to confirm their structures and compositions. The study also investigated the behavior of one of the complexes towards the ring-opening polymerization (ROP) of rac-lactide, aiming to produce polylactide (PLA) with improved physical properties.
