A new class of phytotropins: the monoaralkyl esters of benzene-1,2-dicarboxylic acid

A new class of phytotropins: the monoaralkyl esters of benzene-1,2-dicarboxylic acid. Modena, T.; Pavanetto, F.; Conti, B.; Mazza, M. (Dip. Chim. Farm., Univ. Pavia, Pavia, Italy).Several reagents such as 105578-65-2 is used here. Farmaco, Ed. Sci., 41(9), 707-12 (English) 1986. CODEN: FRPSAX. ISSN: 0430-0920. DOCUMENT TYPE: Journal CA Section: 5 (Agrochemical Bioregulators) Section cross-reference(s): 25 The neg. geotropic effect induced in germinating roots of lentils by a I series was studied. The most active compds. were I (R = 2-naphthylmethyl) [105578-64-1] and I(R = 2-quinolylmethyl) [105578-66-3]. The former was more active than N-1-naphthylphthalamic acid (NPA) and the latter had about the same activity. In decreasing order of activity were I (R = 1-naphthylmethyl) [105578-63-0] and I (R = 9-phenanthrylmethyl) [105578-65-2] which had activity about the same as NPA and then I (R = 4-ClC6H4CH2) [105578-58-3], I (R = 3,4-Cl2C6H3CH2) [105578-62-9], I (R = 9-fluoronylmethyl) [105578-67-4] and I (R = PhCH:CHCH2) [105578-68-5] which were 1 order of magnitude less active than NPA. I (R = PhCH2) [2528-16-7] and I (R = 2-pyridylmethyl) [75277-28-0] were 1 order of magnitude more active than 2-benzoylbenzoic acid. Structure-activity relationships were discussed. .

Single step syntheses of w-9-fluorenylmethyl esters of aspartic and glutamic acids

Single step syntheses of w-9-fluorenylmethyl esters of aspartic and glutamic acids. Belshaw, Peter J.; Adamson, J. Gordon; Lajoie, Gilles A. (Dep. Chem., Univ. Waterloo, Waterloo, ON N2L 3G1, Can.Several reagents with their cas registry numbers 24324-17-2 and 135928-47-1 are used here.). Synth. Commun., 22(7), 1001-5 (English) 1992. CODEN: SYNCAV. ISSN: 0039-7911. DOCUMENT TYPE: Journal CA Section: 34 (Amino Acids, Peptides, and Proteins) A simple one step synthesis of the 9-fluorenylmethyl w-esters of aspartic and glutamic acids is described. Thus, treatment of the amino acid and 9-fluorenylmethanol in THF with HBF4.OEt2 gave w-esters H-Glu(OFm)-OH (Fm = 9-fluorenylmethyl) and H-Asp(OFm)-OH in 35-60% yields. .
