Synthesis of agestricin A, B, C and D

Synthesis of agestricin A, B, C and D. Saini, T. R.In this study， 85563-73-1 and 2426-87-1 are also used.; Pathak, V. P.; Khanna, R. N. (Dep. Chem., Univ. Delhi, Delhi 110 007, India). Indian J. Chem., Sect. B, 22B(10), 1063 (English) 1983. CODEN: IJSBDB. ISSN: 0376-4699. DOCUMENT TYPE: Journal CA Section: 26 (Biomolecules and Their Synthetic Analogs) Agestricin A, B, C and D (I, R = H, R1R2 = OCH2O; II, R = H, R1R2 = OCH2O, R1 = R2 = OMe, R1 = OMe, R2 = OH) have been synthesized from 3-benzyloxy-2,4-dimethoxy-6-hydroxyacetophenone by condensation with piperonal, veratraldehyde and 4-O-benzylvanillin to give the chalcones I (R = CH2Ph), which on acid cyclization afford flavanones II (R = CH2Ph). The latter on catalytic debenzylation furnish II (R = H), identical with the natural samples. .

DOCUMENT TYPE: Patent CA Section: 11 (Plant Biochemistry) The hydroxyphenylalkanoate esters I (R = Me, Et; R1 = H, alkyl; R2 = R1, aryl; R3 = alkyl, aryl) are prepd. as flavorant-releasing tobacco additives. The reaction of vanillin with Et isobutyrate, in Li diisopropylamide-contg. THF, gave I (R = R1 = R2 = Me, R3 = Et). Upon pyrolysis in the tobacco products, I releases vanillin and alkanoic ester flavorants. .
