Cyclothiomethylation of heterochain α,ω-diamines with formaldehyde and H2S
摘要:
Cyclothiomethylation was performed of heterochain (O, S-S, NH) alpha,omega-diamines with formaldehyde and H2S in aqueous medium at 20-60A degrees C to obtain new alpha,omega-bis(1,3,5-dithiazinanes). The cyclocondensation of N-(3-aminopropyl)butane-1,4-diamine (spermidine), formaldehyde, and H2S proceeds efficiently in the medium of BuOH-H2O at 0A degrees C and leads to the formation of previously unknown O,S-containing macroheterocycle, 1,7-dioxa-3,5,9,11-tetrathiacyclododecane. A fungicidal activity was found in 5,5'-(3,6-dioxaoctane-1,8-diyl)bis-1,3,5-dithiazinane with respect to microscopic fungi affecting agriculture.
