  α-AMINO ACID DERIVED BISPHOSPHONATES. SYNTHESIS AND ANTI-RESORFTIVE ACTIVITY

  摘要：

  Eleven new bisphosphonates were prepared from naturally-occurring I-amino acids. The synthesis required special attention to amino and side-chain protections. The novel compounds were tested in TPTX (thyroparathyroidectomized) rats against arotinoid-induced hypercalcemia and were compared to alendronate. Most of the compounds showed moderate to no anti-resorptive activity. Two compounds were more active than clodronate, but less than alendronate. Limited SAR conclusions were drawn.

  The trifluoroborane-catalyzed C–H functionalization/S–H insertion reaction of α-diazophosphonates with thiols has been developed. A plausible reaction mechanism has been proposed to understand the combined reaction. This process provides straightforward access to N,S-acetals containing quaternary centers in moderate to good yields and chemoselectivity.

  Reduction of β-phthalimido-α-keto phosphonates, obtained through an Arbuzov reaction between the appropriate acid chloride and triethyl phosphite, with boranes and oxazaborolidine as catalyst, afforded β-phthalimido-α-hydroxy phosphonates in good yields and high diastereoselectivity. Deprotection of the amino group gave the title compounds.

• 1,2-Hydride Migration in Dialkyl α-Diazophosphonates Catalyzed by [Cu(MeCN)4]PF6: A Novel Approach to β-Amino (E)-Enylphosphonates

  日期：——

  The regiospecific and stereoselective 1,2-migration reaction of dialkyl alpha-diazophosphonates for the synthesis of beta-amino (E)-enylphosphonates is developed utilizing tetrakis(acetonitrile)copper(I) hexafluorophosphate [Cu(MeCN)(4)PF6] as the catalyst and N,N-dimethylformamide as an additive. A possible mechanism for the 1,2-migration reaction involving a metal carbene is presented. An investigation on the E/Z isomer selectivity of this process demonstrates that steric factors play an important role on the outcome. This process provides a straightforward access to beta-amino (E)-enylphosphonates in moderate to good yields.
• Unexpected Stereoselective Synthesis of (<i>Z</i>)-β-Alkenyl Substituted β-Amino Phosphonates through β,γ-Dihydrogen Shift Reaction Catalyzed by a Copper(I) Complex and Iodine [Cu(MeCN)₄]PF₆/I₂

  AbstractA series of dialkyl α‐diazophosphonates has been prepared from natural amino acids. The diazo decomposition of these diazophosphonate compounds with tetrakis(acetonitrile)copper(I) hexafluorophosphate/iodine, [Cu(MeCN)4]PF6/I2, as catalyst has been investigated. It was found that the diazo decomposition of dialkyl α‐diazophosphonates gave a mixture of β,γ‐dihydrogen shift and 1,2‐hydride migration products and afforded β‐alkenyl‐substituted β‐amino phosphonates with the Z configuration. The mechanism of this novel diazo decomposition process was discussed.magnified image
