摘要:Lamellarins are prepared using a solid phase synthesis. In a first aspect, the process includes a step as follows: Formula (I) where R 1 to R 15 are as defined, and X is halogen, provided that one of R 2 , R 3 or R 4 is immobilised to a resin. In a second aspect, the process includes a step as follows: Formula (II) where R 1 ′ to R 5 ′, R 11 ′ and R 13 ′ are as defined, X 1 and X 2 are halogen, M is a metal function and PG is an amino protecting group, provided that one of that R 2 ′, R 3 ′ or R 4 ′ is immobilised to a resin.
