  The first enzymatic resolution of quaternary α′-acetoxy α,β-unsaturated cyclohexenones and cyclopentenones

  摘要：

  The enantio selective resolution of various quaternary alpha'-acetoxy alpha,beta-unsaturated cyclohexenones and cyclopentenones was performed with the commercially available enzyme CCL in pH = 8.0 phosphate buffer. Various parameters that would affect the enantioselectivities were tested and the best enzymatic resolution conditions were found to afford the enantiomerically enriched quaternary acetoxylated substrates with high ee varying between 36% and 99%.

  Objective: To assess the effects of prehospital nitroglycerin (NTG) on vital signs and chest pain intensity. Methods: A retrospective review of advanced life support (ALS) run sheets was performed in a suburban volunteer emergency medical services (EMS) system receiving 8,000 annual ALS calls. All consecutive patients who were administered NTG by EMS were included. Standardized forms were used to collect data on patient demographics, history, and physical exam. Patients assessed their chest pain (CP) before and after NTG on a verbal numeric scale of 0-10 from least to most severe. The presence of syncope, dysrhythmias, or profound hypotension [loss of peripheral pulses, a systolic blood pressure (SBP) of <90 mm Hg after NTG, or a drop of >100 mm Hg in BP] was noted. Results. One thousand six hundred sixty-two patients received NTG over 18 months, their mean age was 66 years, and 48% were female. Indications for NTG included CP (83%), dyspnea (45%), and congestive heart failure (20%). After NTG administration, the CP score decreased from 6.9 to 4.4 (mean difference = 2.6; 95% CI = 2.4 to 2.8). The CP completely resolved in 10% of the patients. Mean decreases in SBPs and diastolic BPs were 11.8 mm Hg (95% CI = 10.7 to 13.0) and 4.0 mm Hg (95% CI = 2.9 to 5.1). The mean pulse rate increased by 2.7 beats/min (95% CI = 0.6 to 4.9). There were 12 patients with adverse events [0.7% (95% CI = 0.4% to 1.3%)], including profound bradycardia and hypotension (1), transient drop in SBP of 100 mm Hg responding to fluids (6), post-NTG SBP <90 mm Hg (4), and syncope (1). There were no deaths in the prehospital setting. Conclusions: Use of prehospital NTG appears safe. While NTG reduces CP, most patients have residual pain.

  Treatment of the E-α,β-unsaturated selenyl esters 1 and 3a with Bu3SnH-AIBN produces the corresponding cyclohexenones 2 and respectively via presumed α-ketene alkyl radical intermediates. In a similar manner the cyclopropyl ester 9 leads to a mixture of 12 and 13, and the 2,7-diene selenyl ester 15 undergoes a novel bi-cyclisation producing the diquinane 17 in 76% yield.

  用Bu 3 SnH-AIBN处理E - α，β-不饱和硒烯基酯1和3a分别产生相应的环己烯酮2，并通过假定的α-烯酮烷基自由基中间体产生相应的环己烯酮2。以类似的方式，环丙基酯9产生12和13的混合物，并且2，7-二烯硒烯基酯15经历新的双环化，以76％的产率产生二喹烷17。
