Tetrahedron Letters is a weekly international journal for rapid publication of full original research papers in the field of organic chemistry. According to the Journal Citation Reports , the journal has a 2022 impact factor of 1.8 [ 1 ]
Tetrahedron is a weekly peer-reviewed scientific journal covering the field of organic chemistry. According to the Journal Citation Reports, Tetrahedron has a 2020 impact factor of 2.1. [1] Tetrahedron and Elsevier, its publisher, support an annual symposium. [2] In 2010, complaints were raised over its high subscription cost. [3]
The Cram's rule of asymmetric induction named after Donald J. Cram states In certain non-catalytic reactions that diastereomer will predominate, which could be formed by the approach of the entering group from the least hindered side when the rotational conformation of the C-C bond is such that the double bond is flanked by the two least bulky groups attached to the adjacent asymmetric center.

The ACS Style is a set of standards for writing documents relating to chemistry, including a standard method of citation in academic publications, developed by the American Chemical Society (ACS).
According to a mechanism proposed by Sweet in 1973 the aldol condensation of ethylacetoacetate 1 and the aryl aldehyde is the rate-limiting step leading to the carbenium ion 2. The nucleophilic addition of urea gives the intermediate 4, which quickly dehydrates to give the desired product 5. [15] The mechanism of the Biginelli reaction
Tetrahedrane is one of the possible platonic hydrocarbons and has the IUPAC name tricyclo[1.1.0.0 2,4]butane. Unsubstituted tetrahedrane (C 4 H 4) remains elusive, although it is predicted to be kinetically stable. One strategy that has been explored (but thus far failed) is reaction of propene with atomic carbon. [2]
Anthony "Bo" Arduengo was born in 1952 in Tampa, Florida. [1] He grew up in the Atlanta, Georgia area. His father was a pressman and mechanic with the Atlanta Journal-Constitution and instilled his son with an interest and skill for all things mechanical and scientific.
