A method for making a compound of formula (I)
wherein bonds a and b are single or double bonds, provided that one of a and b is a single bond and the other is a double bond; one of B1 and B2 is -CHR5-CHR6-C(Y)ZR7, -CR10R11-NHR12 or hydrogen and the other is absent; B3 is -C(W)NHR8 or hydrogen; provided that one of B1, B2 and B3 is not hydrogen; Y and W are O or S; Z is O, S or NR9; R5 is hydrogen or C1-C4 alkyl; R6 is hydrogen or C1-C4 alkyl; R7, R9, R10 and R11 are independently hydrogen, alkyl, alkenyl, aryl or aralkyl; and R8 and R12 independently are alkyl, alkenyl, aryl or aralkyl. The method comprises steps of: (a) preparing an imidazolidinethione having formula
and (b) adding to the imidazolidinethione, without isolation of the imidazolidinethione, one of: (i) CHR5=CHR6-C(Y)ZR7; (ii) R10R11C=O and R12NH2; (iii) R10R11C=NR12; and (iv) R8N=C=W.
一种制备化合物的方法,其化学式为(I),其中键a和键b为单键或双键,前提是a和b中的一个是单键,另一个是双键;B1和B2中的一个是-CHR5-CHR6-C(Y)ZR7,-CR10R11-NHR12或氢,另一个不存在;B3是-C(W)NHR8或氢;前提是B1、B2和B3中的一个不是氢;Y和W为O或S;Z为O、S或NR9;R5为氢或C1-C4烷基;R6为氢或C1-C4烷基;R7、R9、R10和R11独立地为氢、烷基、烯烃基、芳基或芳基烷基;而R8和R12独立地为烷基、烯烃基、芳基或芳基烷基。该方法包括以下步骤:(a)制备具有化学式的咪唑烷硫脲;(b)在不分离咪唑烷硫脲的情况下,向咪唑烷硫脲中添加以下其中之一:(i)CHR5=CHR6-C(Y)ZR7;(ii)R10R11C=O和R12NH2;(iii)R10R11C=NR12;以及(iv)R8N=C=W。
