N-ethoxycarbonyl-2-ethoxy-1,2-dihydroquinoline (EEDQ) gave three hexaglycosyl hexapeptides and a nonaglycosyl hexapeptide derivatives (9, 11, 14, and 17). These N-terminus free compounds were derived from triglycosyl tetrapeptides (3 and 5) or a hexaglycosyl tetrapeptide (7) on selective deblock reaction by morpholine. The hexaglycosyl hexapeptides (10, 13, and 16) and the nonaglycosyl hexapeptide (18)
