1-heteroalkylation of the tris-(trimethylsilyl)phosphine was thoroughly investigated using heterosubstituted methylamines, chloromethyl alkyl ethers, methyl chloroformate, paraformaldehyde, and dialkylformamides. Convenient methods for the synthesis of tris(dialkylaminomethyl)phosphines, tris(alkoxymethyl)phosphines, tris(methoxycarbonyl) phosphine, and several phosphaethylenes were proposed on the basis

trivalent organophosphorus acids to various functionalized acrylates and their cyclic analogues is proposed as convenient methods for the synthesis of new 2-trimethylsiloxycarbonyl-substituted alkylphosphonites and their derivatives under mild conditions. Also the new functionalized derivatives of these phosphonites, including amino, amido, and amino acids fragments as well as certain properties of these

aminomethylation of the several esters of hypophosphorous acid using chloro-, alkoxy-, and amino-substituted methylamines of various structure is proposed as convenient method for the synthesis of newfunctionalizedaminomethylphosphonites and bis(aminomethyl)phosphinates. Also O,O-diethyl(pivaloyl)phosphonite is successfully applied in the aminomethylation as a synthetic analog of unstable diethoxyphosphine.

Novel N-Mannich base-type derivatives of the antimalarial drug amodiaquine were synthesised by reaction with tertiary N-chloromethylamides. With the exception of the derivative of ethylhippurate, all the so-formed (1-amidomethyl-1H-quinolin-4-ylidene)arylamines displayed high chemical and enzymatic stability. These compounds displayed antimalarial activity against the multi-drug resistant Plasmodium
The discovery of selectiveagonists of cannabinoidreceptor2 (CB2) is strongly pursued to successfully tuning endocannabinoid signaling for therapeutic purposes. However, the design of selective CB2 agonists is still challenging because of the high homology with the cannabinoidreceptor 1 (CB1) and for the yet unclear molecular basis of the agonist/antagonist switch. Here, the 1,3-benzoxazine scaffold
