Misplace of Schemes

In the original publication [1], Scheme 1 and Scheme 2 are misplaced due to mistakes in the publication process. Scheme 1 should be placed in the position of Scheme 2 and vice versa.
The correct schemes should be as follows:
Scheme 1. Synthesis of ALa-NHS ester. Reagents and conditions: (a) Br(CH2)4CO2CH3, K2CO3, KI, Bu4NBr, acetone, reflux, 16 h, 75% of 3. (b) Tf2O, pyridine, 0 °C to rt, 20 h, 91%. (c) i. n-BuLi, THF, −78 °C, 40 min; ii. B(OiPr)3, −78 °C to 0 °C, 1.5 h, 93%. (d) Pd(PPh3)4, K2CO3, DMF, 93 °C, 24 h, 75%. (e) i. HCl, MeOH, rt, 22 h; ii. TFA, CH2Cl2, rt, 20 h, 97%. (f) Lipase acrylic resin, THF-PB 100 mM, rt, 20 h, 93%. (g) EDC·HCl, NHS, DMF, rt, overnight, 99% of crude product.

Scheme 2. Synthesis of ALb-NHS ester. Reagents and conditions: (a) Pd(PPh3)4, K2CO3, DMF, 95 °C, 19 h, 77%. (b) NaH2PO4·H2O, NaClO2, tBuOH-H2O (5:1), rt, 5 h, 96%. (c) iPrOH, THF, conc HCl, 55 °C, 24 h, 98%. (d) Br(CH2)4CO2CH3, Cs2CO3, DMF, 94%. (e) Lipase acrylic resin, THF-PB 100 mM, rt, 20 h, 99%. (f) EDC·HCl, NHS, DMF, rt, overnight. (g) 5% Pd/C, acetone, H2 (1.5 atm), rt, 19 h, 95% of crude product from 14.
Scheme 2. Synthesis of ALb-NHS ester. Reagents and conditions: (a) Pd(PPh3)4, K2CO3, DMF, 95 °C, 19 h, 77%. (b) NaH2PO4·H2O, NaClO2, tBuOH-H2O (5:1), rt, 5 h, 96%.
