The synthesis of stable guanofosfocin analogues has attracted considerable attention in the past 15 years. Several guanofosfocin analogues mimicking the three constitutional elements of mannose, ribose, and guanine were designed and synthesized. Inte

Heteroatom analogues of hydrocodone, in which the N-methyl functionality was replaced with oxygen, sulfur, sulfoxide, and sulfone, were prepared by a short sequence from the ethylene glycol ketal of hydrocodone; a carbocyclic analogue of bisnorhydroc

N-Oxides derived from oxycodone and O-acyloxymorphone were treated with the Burgess reagent to provide the corresponding oxazolidines in excellent yields. Oxazolidines derived from O-acyloxymorphone were further hydrolyzed to noroxymorphone, whose al

Heating ortho-nitro-anilides 1–3 and 2-methyl-N-(3-nitropyridin-2-yl)propanamide (5) with 4 equiv. of a phosphine led to the 2-substituted benzimidazoles 6–8 and to the imidazo[4,5-b]pyridine 10, respectively, in yields between 45 and 85%. Heatin

Guanofosfocins are strong inhibitors of chitin synthases, but also very prone to hydrolytic cleavage. Two advanced intermediates 15 and 20 for the synthesis of stable di-carba-guanofosfocins were prepared via ester 11. Acylation of the allylic C-glyc
