Abstract

Title cpds. are of formula (I):- (where R3 is (a) H, CH3, C2H5 or -CH(CH3)2 or (b) a >=16C satd. linear aliphatic chain directly linked to N; R3' is (c) H, CH3, C2H5 or -CH(CH3)2 or (d) a >=14C satd. linear aliphatic chain directly linked to the structure; R6, R7 and R8, are (e) H or an electron donating or accepting gp. or (f) a >=16C satd. linear aliphatic chain opt. linked to the structure via an ether gp., >=1 R3, R3', R6, R7' and R8' being a satd. linear aliphatic chain).
