A 2,2-Bis(ethoxycarbonyl) vinyl- (BECV) group was used for the selective protection of amines at room temperature in the presence of potentially interfering functional groups such as OH, SH, COOH as well as other NH 2 groups. Several functional group transformations such as esterification, O-alkylation, O-acylation, N-alkylation, N-acylation, S-alkylation can selectively be carried out in the presence of the BECV group. The selective deprotection of the BECV group was achieved in a short time using ethylenediamine at room temperature while several other functional groups such as benzoate, aliphatic esters, amides and ethers remain intact. The BECV group shows orthogonal stability against the common protecting groups such as Fmoc, Cbz and Boc.

Herbicidal methods employing anilino compounds having the formula: EQU1 wherein R and R1 are selected from the group consisting of hydrogen and methyl; R2 and R3 are selected from the group consisting of CN and COOY, where Y is an alkyl group having from 1 to 8 carbon atoms; X is selected from the group consisting of lower alkyl having 1 to 4 carbon atoms, lower alkoxy having from 1 to 4 carbon atoms, nitro, trifluoromethyl, and halo; and n is an integer from 0 to 2, are disclosed.
