E.General Method for Esteriﬁcation.EDC HCl (4 mmol ×
free OH) was added in one solid portion to a solution of DMAP
(0.6 equiv in SM) PEG-COOH (4 mmol × free OH),and either
Lam-D (15)or 18 (1 mmol) in dry CH2Cl2 (45 mL).The
resulting solution was stirred at r.t.for 3 h.The reaction mixture
was diluted with CH2Cl2 and washed with sat.aq.NaHCO3 and
brine.The organic phase was dried over anhydrous MgSO4,and
the solvent was removed under vacuum.The residue was
directly puriﬁed on silica gel to provide compounds 8,9,19a f
(40% quant.yield).
