binding to Na+,K+-ATPase, is described. The key step involved a cyclization to the isoquinoline ring under Pictet-Gams conditions which was best performed with the 6-hydroxy group protected as the benzylether. When an unsaturated ester group was present in position 4 of the 1-benzyl group, this was best introduced before the cyclization step, since the IIeck reaction on 1-(4-bromobenzyl)-6-hydroxyisoquinoline

A manufacturable technology for the production of an antiviral composition containing phosphonoacetic acid, involing РН-alkylation of dimethyl phosphite with methyl chloroacetate under phase-transfer conditions and subsequent in situ hydrolysis of the intermediate product, was developed. The composition showed expressed antiviral effect against herpesviral infections caused by herpes simplex virus
