—— | (E)-3-((S)-2-(dibenzylamino)-4-methylpentylidene)-dihydrofuran-2(3H)-one | 1447927-59-4 | C24H29NO2 | 363.5 |
The enantiospecific synthesis of the diacid side-chain of deoxyharringtonine (2) and homodeoxyharringtonine (3) was accomplished from (L)-N-Boc-α-amino alcohol 10 in high yield. A key feature of the synthesis is the construction of the chiral tertiary alcohol by a three-step sequence (i.e., Wittig reaction, Meisenheimer rearrangement, and catalytic hydrogenation).
