Gong, Young-Dae published the artcileConstruction of 6-Amino-2,2-Dimethyl-3,4,6-Trisubstituted-2H-1-Benzopyran Library by Solid Phase Synthesis, COA of Formula: C7H5Br2F, the publication is Journal of Combinatorial Chemistry (2003), 5(5), 577-589, database is CAplus and MEDLINE.
A library of functionalized derivatives of aminodimethylbenzopyran I is prepared on solid support. Resin-bound p-hydroxybenzyl alc. is converted to its p-nitrophenyl carbonate; treatment with I yields resin-bound I. N-alkylation of resin-bound I followed by cleavage with trifluoroacetic acid in CH2Cl2 yields N-monoalkylated derivatives of I. Oxidation of the N-alkylated resin-bound I with m-chloroperbenzoic acid followed by addition of an alc. yields resin-bound dialkoxyaminobenzopyrans stereoselectively. Cleavage of the resin-bound dialkoxyaminobenzopyrans from the resin yields alkoxyaminobenzopyranols; alkylation with alkyl halides or acylation with acyl chlorides followed by cleavage from the resin yields either dialkoxyaminobenzopyrans or alkoxyaminobenzopyranol esters stereoselectively. The reactions of some of the resin-bound intermediates are monitored by ATR-FT-IR and HR-MAS-NMR spectroscopy.
