Compounds with bridgehead nitrogen. Part 43. The reaction between trans-2-aminocycloalkanethiols and formaldehyde
Abstract
trans-2-Aminocyclopentanethiol condenses with formaldehyde to give rel-(3aR,6aR,9aR,1 2aR)-6,12-methanoperhydrodicyclopentano [d,i][1,6,3,8]dithiadiazecine whereas trans-2-aminocyclohexanethiol and trans-2-aminocycloheptanethiol give 1 : 1 mixtures of diastereoisomeric bis(perhydrocycloalkanothiazol-3-yl) methanes.
