Thiocarbamides 6- membered

Chemical structures for molecules in this category, i.e. (1)-(12) [31 0] are shown in Scheme 6.4 and geometric parameters are collected in Table 6.1. The key feature of these structures is that, by virtue of its incorporation within a five-membered ring, the thiocarbamide adopts a syn configuration which, presumably, will favour the adoption of the / 2(8) ring synthon.
