—— | tert-butyl (S,E)-1-(dihydro-2-oxofuran-3(2H)-ylidene)-4-methylpentan-2-yl-carbamate | 1447927-57-2 | C15H25NO4 | 283.368 |
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).
