78265-39-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 78265-39-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,2,6 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 78265-39:
(7*7)+(6*8)+(5*2)+(4*6)+(3*5)+(2*3)+(1*9)=161
161 % 10 = 1
So 78265-39-1 is a valid CAS Registry Number.

Preparation of Polyfunctionalized Aromatic Nitriles from Aryl Oxazolines

Hess,Guelen,Alandini,Mourati,Guersoy,Knochel

supporting information, (2021/12/06)

A selective ortho,ortho’-functionalization of readily available aryl oxazolines by two successive magnesiations with sBu2Mg in toluene followed by trapping reactions with electrophiles, such as (hetero)aryl iodides or bromides, iodine, tosyl cyanide, ethyl cyanoformate or allylic bromides (39 examples, 62–99 % yield) is reported. Treatment of these aryl oxazolines with excess oxalyl chloride and catalytic amounts of DMF (50 °C, 4 h) provided the corresponding nitriles (36 examples, 73–99 % yield). Conversions of these nitriles to valuable heterocycles are reported, and a tentative mechanism is proposed.

BENZ-FUSED LACTONES I. SYNTHESIS OF 3-METHYL-1(3H)-ISOBENZOFURANONES

Boulet, Camille Andre,Poulton, Gerald Arthur

, p. 405 - 410 (2007/10/02)

Unsubstituted and 3-alkyl substituted 1(3H)-isobenzofuranones are readily prepared in good yields via ortho-metallation of appropriate aromatics.

Chemistry of Aryloxazolines. Applications to the Synthesis of Lignan Lactone Derivatives

Meyers, A. I.,Avila, Walter B.

, p. 3881 - 3886 (2007/10/02)

The syntheses of several lignan lactone derivatives using aryloxazolines as the pivotal intermediates have been investigated.Metalations on naphthyloxazolines followed by electrophilic addition gave one of the appropriate substituents, whereas methoxy dis
