Sidky, M. M. published the artcileOrganophosphorus compounds. XVII. Synthesis and isomerization of some basic phosphorothioate esters, Related Products of piperidines, the publication is Egyptian Journal of Chemistry (1973), 43-52, database is CAplus.
Phosphites (RO)2POR1 (R = Me, Et, CHMe2; R1 = CH2CH2NMe2, CH2CH2NEt2, 1-methyl-4-piperidyl, 1-ethyl-4-piperidyl, 1-methyl-3-piperidyl, 1-ethyl-3-piperidyl, 4-methyl-piperazinoethyl) were prepared in 83-95% yield by treating (RO)3P with R1OH. (EtO)2P(S)OR1 (R1 = 4-methylpiperazinoethyl, CH2CH2NEt2, 1-ethyl-3-piperidyl, 1-ethyl-4-piperidyl) were obtained by treating (EtO)2POR1 with S and isomerized to (EtO)2P(O)SR1 on heating.
Egyptian Journal of Chemistry published new progress about 13444-24-1. 13444-24-1 belongs to piperidines, auxiliary class Piperidine,Alcohol, name is 1-Ethylpiperidin-3-ol, and the molecular formula is C6H6INO, Related Products of piperidines.
