Structure-activity studies of configurationally rigid arylprostaglandins
摘要:
Potent, albeit nonselective, smooth-muscle stimulant activity has been previously reported for 16-phenoxy- and 17-phenylprostaglandins, a finding that led to the design and development of the tissue-selective uterine stimulant sulprostone. As an extension of this work, analogues incorporating the 16-phenoxy and 17-phenyl substituents into the rigid indanyl, tetrahydronaphthyl, dihydrobenzofuryl, and dihydrobenzopyranyl ring systems were prepared and evaluated for uterine stimulant activity in vitro and diarrheal effects in vivo. Since these cyclic groups, with the exception of the indanyl, contain a chiral center, both optical antipodes were prepared. These studies demonstrate that ring size, heteroatom, and absolute configuration at C-16 are important determinants for potency and selectivity.

insertion reactions of α-diazo esters. The reactivities and enantioselectivities of Cu complexes of the synthesized bisoxazoline ligands were lower than those of ligands without central chirality. However, planar chiral [2.2]paracyclophane-based bisoxazoline ligands with an inserted benzene spacer that had a sterically demanding isopropyl substituent showed good enantioselectivities in inter- and intramolecular
Enantioselective Copper-Catalyzed Intramolecular Phenolic OH Bond Insertion: Synthesis of Chiral 2-Carboxy Dihydrobenzofurans, Dihydrobenzopyrans, and Tetrahydrobenzooxepines
Efficient: A copper‐catalyzed enantioselective intramolecular insertion of carbenoids into phenolic OHbonds has been developed. This method can be used for the synthesis of the title compounds in high yields and excellent enantioselectivities under mild and neutral conditions (see scheme).
