The biologically important monoalwl ester\*' (I) of l,P-discyl-z-glycero-3-phoephorio acid2 (II) are prepared mostly by multistep syntheses3 in nhiah the phoephate eater bonds are created by the reaction of phosphoryl chloride8 with alcohols, or alkyl iodide6 with silver phosphate derivatives. The d
A convenient and general method has been developed for directly converting bis-nitriles to cyclic diamidines using reagents derived from diaminoalkanes saturated with hydrogen sulfide. A 1:1 mixture of a diaminoalkane and ethyl alcohol (or without) was effective in most cases (72-88%). The synthetic
Benzylidene acetals are cleaved to hydroxyesters by means of a reagent system composed of 2,2'-bipyridinium chlorochromate (BPCC) and m-chloroperbenzoic acid. Oxidative cleavage of a 4,6.O-benzylideae glucose derivative affords a 6-O-beazoyl derivative.
