Abstract

The synthesis of functional and complex organic compounds is majorly performed by the Claisen rearrangement method. Claisen rearrangement is one of [3,3] sigmatropic rearrangements, a complex method in the synthesis of organic compounds, where it is mostly used to construct stereoselective compounds. It can be combined with other synthesis methods to synthesize organic compounds giving satisfactory results based on the method used, temperature, time, and yield produced. This review aimed to summarize several recent advances in synthesizing organic compounds through Claisen rearrangement reactions. An understanding of the mechanism and applications of this reaction might improve the ability to synthesize innovative and useful organic compounds in various fields of life sciences.

Abstract

Sungkai (Peronema canescens Jack.) merupakan tanaman yang secara tradisional dimanfaatkan oleh masyarakat Kalimantan sebagai obat herbal, terutama melalui rebusan daun dan kulit batangnya. Namun, penelitian mengenai keberadaan dan potensi bakteri endofit pada tanaman sungkai masih sangat terbatas, padahal bakteri endofit diketahui hidup dalam jaringan tanaman dan berpotensi menghasilkan metabolit sekunder bioaktif. Tujuan penelitian ini adalah untuk mengisolasi isolat bakteri endofit yang berasosiasi dengan daun sungkai. Metode penelitian dilakukan dengan isolasi bakteri endofit dari daun sungkai, dilanjutkan mengkarakterisasi jumlah isolat yang diperoleh melalui pengujian maksroskopis Hasil penelitian menunjukkan bahwa isolat bakteri endofit dari daun sungkai berhasil diisolasi dan diperoleh satu isolat bakteri endofit dari daun sungkai, dengan karakter makroskopis berbentuk bulat, dengan permukaan datar dan warna krem.
