L-733,725, a new immunosuppressant drug candidate, was prepared by a highly chemoselective alkylation of the macrolide ascomycin at the C32 hydroxy position with the imidazolyl trichloroacetimidate 16. The trichloroacetimidate-activated side chain 16 was prepared by an efficient four-step sequence in 42% overall yield. The high chemoselectivity in the alkylation of the C32 hydroxy group of the unprotected
